Review of Canon PowerShot SX1IS 10 MP CMOS Digital Camera with 20x Wide Angle Optical Image Stabilized Zoom and 2.8-inch LCD

Quick summary:

1. I really like this camera, especially being able to take HD video and optically zoom while recording.I also really like taking 4 fps of continuous shooting.

2. You really need to read (at least skim) through the instructions.Some of the ease of use benefits of a point-and-shoot were compromised to give you some of the versatility of a digital SLR.I'm not too crazy about the "Control Dial" to select menu options.Over all, the software seems a bit less intuitive than other Powershots I've used in the past.

3. Using Quicktime on Windows to view the HD video might result in jerky motion.HD video is smooth in Quicktime on a Mac.This is a Quicktime/Windows issue, not a camera problem.

4. The camera is solidly built, but it's a bit heavy.It's not ergonomically designed for extended video recording.

5. Consider reading and viewing a video demo by a professional at www.cameralabs.com/reviews/Canon_PowerShot_SX1_IS/

Long version:

I was very eagerly anticipating this camera.The key feature in the Canon SX1IS is the CMOS sensor used in the SLR product lines.I got really excited about a single camera with HD video, 20x optical zoom, 4 frames per second of continuous shooting, articulated screen, and standard AA batteries.I've owned several Canon Powershot models, and I've been very satisfied with them.I'm also an experienced 35mm SLR person.I thought that the SX1IS was going to be my perfect camera... or actually the perfect gift for my wife.

I am an amateur photographer whose primary subjects are my children playing sports.Since I work a lot, my wife actually ends up taking a majority of the photos.I was planning to get a digital SLR for her when I came upon the specs for the SX1IS.It seems as if Canon product managers have listened to everything I wanted in a digital camera.The biggest deals for me were

1. HD video with optical zoom enabled while you're filming
2. 4 frames per second of continuous shooting
3. 20x optical zoom
4. Ease of use of a point-and-shoot

Here are my series of reactions:

1. After the first set of photos and videos, I couldn't help but feel as if Canon has under-delivered on the promise of a nearly perfect camera for amateurs or perhaps my camera was defective.This was my review of the first batch of photos and videos:(please read on to the next section since my initial disappointment resulted more from ignorance and unfair expectations)

a. I wasn't getting anywhere near 4 frames per second.

b. In the AUTO mode, the photos seem to come out at a lower quality than my much cheaper Powershot A710 in AUTO mode.By lower quality, I mean that the color, contrast, and details appear not as good.

c. It is very cool to be able to zoom in and out while you are taking video, but the HD video footages came out jerky enough to be really annoying.

2. This didn't seem right, so I actually read the instructions and spent a few minutes googling for info.It quickly became clear that you really have to read the manual to use this camera effectively.The manual is not written especially well, but it contains the info you need.(FYI, I've NEVER read instructions on any of my other digital point-and-shoot cameras before, and I have been very happy with the thousands of photos I've taken.)

a. Getting 4 frames per second:I learned that you cannot shoot 4 frames per second in AUTO mode or SPORTS mode.SPORTS mode can only take continuous AutoFocus photos which is about 1 frame per second.Most of the other modes support fast 4 frames per second continuous shooting.In the 4 fps continuous shooting, only the first shoot will be in focus, the others will be out of focus if the subject moves towards or away from your camera.

b. Comparing photos from SX1IS with A710:I realized that I was taking photos at high zoom that the Powershot A710 was not even able to get, so this was not a fair comparison.For apples-to-apples outdoor photos, SX1IS does take superior photos, but indoor photos does seem grainier at similar zoom levels.However, the difference is really minor, and there are many many adjustments on the SX1IS that can more than compensate.

c. Jerky HD video playback:This is a really a problem with Quicktime on my Windows Vista (on 2.5GHz Quadcore CPU with 4GB of RAM & ATI Radeon 512MB graphics card, so not a hardware issue).I saw similar jerky playback with Quicktime on Windows XP.However, the videos play smooth and perfectly in Quicktime on a Mac OS X.By reading this review, I hope you don't get upset when your first HD video looks really bad because of the jerky motion.I'm sure that this is a temporary problem: either Apple will improve Quicktime playback on Windows, a better MOV player will be available, or software will be available to convert the MOV to another format that works better on Windows.

d. Further note:To make changes to a bunch of settings via the menu options, you have to use this ring on the function button (called the "Control Dial").It's the knurled outermost concentric ring surrounding the FUNC. SET button.You rotate this to select the menu options you want.Well, maybe I'll get used to it, but right now, this ring sucks.It's easy to miss the your menu item because you rotate this ring with just enough force, but if you press a bit too much, you end up with different options.This will probably suck to another plateau when I'm in bright sunlight looking through the viewfinder.

Here are 3 other things you might want to consider before purchasing this camera:

1. The camera feels very solid, but this also means that it is a bit heavy.

2. The form factor is for taking photographs, so if you plan to use this primarily for the HD video, your hands/arms will tire out.It is a bit awkward to keep the camera steady for extended video.HD camcorder will probably be better for you if your primary motivation is to take HD videos.

3. See a professional review with a video demo at www.cameralabs.com/reviews/Canon_PowerShot_SX1_IS/

I'm now having a great time taking lots of photos and videos with this camera.The 20x zoom, HD video, and 4 fps is worth the cost premium.

Review of Canon EF-S 18-55mm f/3.5-5.6 IS SLR Lens

PROS
* Very sharp across the image, even wide open.
* Low Chroma.I read a test ([...]) that found higher than normal amounts of CA in this lens at some apertures, but I don't see it.My standard test is to shoot bare tree limbs on bright sunny days & look for purple fringing, especially at the edges. I'm not seeing anywhere near the level of fringing shown in some of their test shots.If anything, I'd call it "low" I read elsewhere that one of Canon's goals in adding the aspherical element to this lens was to reduce CA, so I'm thinking maybe the lens tested in photozon.de was just a bad apple.
* Image Shake control works.I can't attest to how often it provides a full 4 stops worth of shake reduction, but I can see a very clear result when using it.
* Fast accurate focusing. One of the reasons I purchased this lens was because I was dissatisfied with the performance of my (more expensive) Sigma 17-35 EX (the newer model), which while sharp, is just too slow and inaccurate a focuser for close work in action sports. The new Canon solved that problem.
* Compact, light weight & unobtrusive.Not much bigger than a normal lens.
CONS
* Barrel Distortion at 18mm (28mm) While not exsessive for an inexpensive lens, this is one area where you will see benefit from spending hundreds of dollars for a much more expensive Canon "IS" or "L," or buying a fixed focal length lens. In most real world situations, itwasn't all that noticeable. I could usually correct for it in Photoshop, but this is not a lens for critical architectural work etc. I have taken hundreds of photos with this lens and barrel distortion has only called attention to itself a few times. I suspect this is one price paid for the very compact design.
* Not very fast. Another area where an "L" has an edge. At F3.5 28mm equivalent andF5.6 85mm this lens is relatively slow compared to a pro lens. This effects stopping the action in low light. OTH, you will have to spend hundreds more to get a usable top speed of F 2.8 and that is *only* one stop faster at 28mm equiv. I think both this lens' sharpness and the IS system mitigate this "Con."It took me a while to learn that I could shoot wide open at all focal lengths without having the outer third of the image turn to mush.That's pretty amazing for a zoom at this price. You don't have a stop or two you almost never use because it is too soft. And the IS system works well in low light, though that doesn't figure in in stopping the action.
* Does not have that red stripe.Sad to say, some will never buy this sharp, handy little lens because in is not an "L" and/or doesn't cost $[...].Yes, it does does look a little "plasticy," probably doesn't have the build quality for heavy, everyday use by a real working pro, and does not look massive mounted on your camera body, like a "fast" pro lens that's squeezing out that last F stop. But IMO, it looks very similar to Canon's newer IS lenses, so there is no scarlet letter immediately identifying you as "cheap." In other words, "Get over it."

So, why did Canon produce such a good lens at such a bargain price? I'd say that it's because Nikon announced their intention to do the same a little while ago. Also, Canon's old non IS 18-55mm lens had the rep of being something of a dog. Finally, several competing cameras now have IS built into the body. Canon had to respond with a sharp IS lens that they could put on the Rebels & the 40D. In terms of sales, the low end of the DSLR market is both hot and very competitive.We're the beneficiaries.

Product Description:
Equipped with Canon's Optical Image Stabilizer (IS) technology, the Canon EF-S 18-55mm standard zoom lens is ideal for just about any application. IS technology compensates for camera shake by providing the equivalent effect of a shutter speed up to four stops faster. This allows you to take sharp handheld shots even in low-light conditions--a must for sports and nature photography. The lens also offers an aspherical lens element that corrects for aberration, thus producing a topnotch image throughout the zoom range, and a circular aperture that exquisitely renders out-of-focus backgrounds. Despite its minimal size, weight, and cost, the lens expands the picture-taking possibilities any time slow shutter speeds are needed.
Specifications
  • Focal length: 18 to 55mm
  • Maximum aperture: f/3.5 to f/5.6
  • Lens construction: 11 elements in 9 groups
  • Angle of view: 74 degrees @ 20 feet to 27 degrees @ 50 feet
  • Focus adjustment: Autofocus (DC motor) with manual focus option
  • Closest focusing distance: 9.8 inches
  • Filter size: 58mm
  • Dimensions: 2.7 inches in diameter and 3.33 inches long

Review of Canon PowerShot SX20IS 12.1MP Digital Camera with 20x Wide Angle Optical Image Stabilized Zoom and 2.5-inch Articulating LCD

Let me start off by saying that I'm not a professional photographer.My decision to purchase the SX20 IS was based on a desire to get an excellent still shot camera, with high capacity zoom, that also had HD Video (720p) capabilities.So, I began my research and spent many hours scouring the web to make an informed decision.I had narrowed my choice to the Canon SX20 IS and the Panasonic DMC-FZ35.

Here are some of the key specs of each camera:

Optical Zoom (Canon: 20, Pana: 18)
Still image files (Canon: Not Raw, Pana: Raw)
Articulating LCD (Canon: Yes, Pana: No)
720p HD video per 2 GB (Canon: 10 min 33 sec, Pana: 15 min)
Video file format (Canon: .mov, Pana: AVCHD Lite)
Battery Type: (Canon: 4 AA, Pana: Li-ion rechargeable)
Stereo Audio (Both)
SD Card Storage (Both)

[...].

In the end I decided to go with Canon for a few key reasons:

#1. The articulating LCD (pull out, tilt/move) was a key factor, as I wanted to be able to shoot from many different angles.It came in handy very soon--the second time I used the camera--I was able to whip out the LCD and get some decent shots at a football game when I had to raise the camera high over my head to shoot over the folks standing in front of me.

#2. The ability to easily share video files.The .mov file format is a more widely accepted format, which can easily be shared (without processing/conversion).The files are accepted on sites such as You Tube. The files can be played with Quicktime and other media players (e.g. VLC).Although the Panasonic camera uses a format which is more compressed and allows more data to be stored on an SD card, the file format is not as wide spread and not as easy to share with others, without converting the file.

#3. Consumer Reports rankings for last year's model: Canon #1, Pana #5 (SX10 IS & Pana DMC-FZ28). I suspect the SX20 IS will follow the same trend this year when Consumer Reports releases their test results for 2009.

#4. Canon takes AA batteries.This makes the camera slightly heavier, but you'll always be able to get economical batteries in a pinch, without the need for buying a proprietary lithium ion battery.May I recommend Sanyo Eneloop rechargeable batteries. I bought some new on Amazon. They are excellent. I haven't charged them yet and I've taken 120 pictures and 40 minutes plus of 720p video. I've also played back the pictures and movies on my TV/Projector and transferred all files to my computer, using the same batteries, without charging them.And they are "..still going..."

Here are some sample pictures taken with the SX20 IS.Keep in mind that Flickr doesn't display the full, original picture which was taken in maximum resolution (in auto mode). [...].

I've taken some great up-close family shots and macro shots.They look great and are very detailed. I took some night/action pics (with the flash) and adjusted the shutter speed and ISO settings and the pictures looked great, given the conditions.

[...].

I apologize for the camera jitter in advance as I didn't have a tri-pod and I was in a tight area in the Stadium when I took the shots.

I must admit that I am thoroughly impressed with the video quality/resolution.I shot sample video from my 1 year old camcorder (Panasonic SDR-H40, a standard definition hard drive camcorder) and shot the same footage with the SX20 IS. The difference in quality was amazing.Not only was the Canon much sharper, but the richness and vibrance of the colors was so much better. I sold my SDR-H40 on Ebay within two days.I now will have only one camera to shoot stills and 720p HD video--the Canon SX20 IS. The videos from the SX20 IS looked awesome--on both my 32 inch 720p LCD and my 100+ inch screen via a 720p DLP projector. I connected the camera with an HDMI cable and bam, I was ready to watch great video and view still shots "on the big screen."See the above referenced links for video footage yourself.If I were given the opportunity to watch a football game shot in standard definition by ESPN or an HD version of the same game, shot with the SX20 IS (on a tripod, without my hand jitter), I'd pick the latter in a heart beat.

No buyer's remorse here!If you are looking for an SLR type camera, that does awesome stills and great 720p HD video (both zoomable at 20x optical), you'd be hard pressed to get more bang for your buck then the SX20 IS on Amazon.

One minor issue I've noticed is that when zooming in/out while shooting video, you can here a slight "click" when you initiate the zoom and when you stop the zoom.There is NO noise heard while the lens is zooming/telescoping in/out; the "click" is only heard when the zoom is initiated and when the zoom is stopped.The "click" is not that noticeable. I had to shoot footage in silence, after the kids had gone to bed, in order to distinguish the "click."In most shooting environments I don't expect it to be much of an issue.

Best of luck with your purchase decision.

P.S.By the way, the owner manual states that you must use the Canon software to transfer images/movies from the camera to a PC, else movies will not transfer (frames will be dropped) correctly and images shot vertically may be transferred in the horizontal orientation. So, don't just do a copy/paste of the files them self from the SD card.Keep this in mind as you view sample video on the web.

Review of Canon Image Stabilized 12x36 II Binocular

These replaced an older version of these binoculars. The new ones are much lighter and the view seems to be brighter. While I do wish the IS button would toggle, it really is not much of an issue. However for the price it would be nice if Canon would include a hard case and some type of protection for the eyepeices, I wear glasses and with the rubber eye cups folded down the eyepeice lenses are very exposed. Overall I give these binoculars 5 stars.

Review of Canon 8x25 Image Stabilization Binoculars w/Case and Neck Strap

They are, and they aren't, great binocs
What they are: as it says, the lightest and least expensive IS binoculars on the market (right now). The optics themselves are only merely very good, but - HAND HELD - with the IS activated, they allow me to read fine print about 20% closer than with my Leica 8x32 Ultras. On a rest, the Leicas are superior. It's the elimination of the jiggles - the 8x25 Canons don't give an image that's as bright and contrasty as those high dollar Leicas, but the steadier image more than makes up for that.
What they aren't: waterproof or armored. So have a care if you use them in conditions of rain or dust. They're much more complicated than simple binocs, with electric circuits inside, and the matter of reliability does come into consideration - but in the first year, they've survived life in the tote bag ,bouncing along dirt roads without a hiccup.Two more things: besides armoring and ruggedizing, Canon had to compromise _somewhere_ to make them this small. So, while the IS deals well with rapid human shaking. it doesn't seem to correct at all for slow motions. I imagine the engineers were forcd to leave off the sensors for slow motions, to fit everything else in. And, they use CR123 batteries, more expensive and harder to find in a pinch than AA batteries. Of course, if the batteries run dead, all your are left with is a functional set of very good, if a bit bulky, 8x25 binocs. What Canon has created is $300 binoculars that - hand held, with the IS active - outperform my high dollar Leica 8x32 Ultras. And, I imagine, the Nikon SE's, too. No kidding.

Product Description:
Whether you are sitting in the nosebleed seats of a stadium or an opera house, with Canon's 8 x 25 IS binoculars you'll get an outstanding close-up view of the action. The binoculars are designed to fit perfectly in your hands and have a rubber coating for nonslip grip and protection from damage. The focus dial is center-mounted and the image stabilizer controls are easily accessible from either hand. Canon's optical image stabilization technology eliminates shake and reduces curvature of field. The image stabilizer operates with a CR123A Lithium battery. The lenses are coated with Super Spectra multicoating that improves image quality by maximizing contrast and minimizing color smear.
Image Stabilization and More
With any high magnification binoculars, most users will experience frustrating image shake. Unless fixed to a tripod, image shake can render high magnification binoculars useless. Canon's IS technology is remarkably effective at eliminating this problem and is widely used by the television industry with Canon's professional broadcast quality video recording equipment. A special VAP (Vari-Angle Prism) corrective IS system sits between the objective lens group and the porro prism on each side of the binoculars. Within thousandths of a second of the binoculars being moved from their optical axis by vibrations, a detection system activates the IS mechanism. The VAP shape alters to refract or 'bend' the light path by precisely the right amount, thus fully compensating for the vibration. It is this essentially immediate response that effectively suppresses image shake.
Super Spectra Coating
A number of optical factors affect the brightness of an image, including the amount of incidental light that is reflected by the lens. An uncoated lens will refelect away as much as 8% of the incidentail light, significantly dimming the image. Canon's Super Spectra Coating prevents that reflection.
What do the numbers mean?
15x50? 8x25? The two numbers used to describe any pair of binoculars are their magnification - 8x, 12x, 15x and so on - and the diameter of their objective lenses - 25mm, 36mm, 50mm, and so on. The larger the first number is, the larger the object will appear to be in the objective lens. For instance, if you use a 10x lens and look at an object that is 100 yards away, it appears to be the same size as an object located just 10 yards away. The second number, the size of the objective lens, is important because the larger the objective lens, the more light it can admit for brighter, more detailed images, and the better suited they will be for lowlight situations.

Review of Canon 18x50 Image Stabilization All-Weather Binoculars w/Case, Neck Strap & Batteries

Right out of the box, these binoculars, no doubt are one of the best pair of optics I have ever purchased. The Image Stabilization feature is what makes the bincoluars so attractive...and expensive.

They work great on the water or in situations that will reduce hand shakieness.

I own a pair of 10x30 Canon and wanted to upgrade having liked them.

With the 18x50 I got what I expected with the 10x30 model, but the weight of these bincolars is a bit of a draw back. At least they have a tripod hole for support if you need it.

The weight also creates another draw back.

**** Be aware, there appears to be a design flaw with the top eye peice portion. Due to the heavy weight of these 18 x 50 binoculars, one must be careful how you handle them.

These binoculars have a different method for their case carrying strap then the other Canon image stablization binoculars. Other models have a strap for the case and another neck strap for the binoculars themselves.

On the 18 x 50 model it uses the same neck strap, for both the bincoular and the case. Simply, the case has no strap and you place the binoculars in the case and pull neck strap out from the case, over the top case flap and use it as the case's carrying strap.

On first look, it seems like a better idea.

The neck strap attaches to the eye peice portion of the binoculars, while the other 'lighter' models have the neck strap attaching to the body itself. This causes the weight of the entire units to be supported on the eye piece portions.

Having only had these 18x50 IS binoculars less than three weeks from purchase, I pulled the binoculars out of the case when the top eye piece portion separated from the main body. This waswith little pressure and being careful everytime I handled them.

I figured it was a simple fix, perhaps snapping pieces back in place. This was not the case. On closer inspection the fastening screws, which held the eye piece portion to the main body, were still in tack, but the screw holes, which kept the main body to the eye peice in place, appeared not to be strong enough to handle extra pressure.

The outer loop of the screw holes on two of the three screw holes broke away.

The screws are set too close to the outer part of the eye peice base for strong enough support and the material supporting the screw holes are too weak to support the existing body weight and pressure exerted on it over time.

This breakage came with little effort and pressure or from abuse.

I thought about repairing them myself, but figured it still was under warranty (only 3 weeks old) and the cost of $1,100 should be enough excuse to send them to Canon Repair for a quick fix.

BOY WAS I SADLY MISTAKEN. Canon Repair charged me another $350 to repair it and it's now over 4 weeks and I have not seen them yet. I've owned them less than 8 weeks and more than half of that time is in repair!

I just wonder if anyone else has had this problem as it certainly appears it's a design flaw because of the overall weight.

So to review them I would say great binoculars but becareful on how you handle these items, if you need a good pair of binoculars, I would say go with the lower models of the Canon IS series as they are more durable!

Product Description:
Canon's 18x50 IS binoculars incorporate an optical image stabilizer for shake-free viewing and minimal eye fatigue. This technology was first developed for Canon video camcorders and is now available in many of Canon's binoculars. The system employs a Vari-Angle Prism, dual transparent plates, independent vertical and horizontal sensors, and a dedicated microprocessor to continuously adjust the prism to maintain a steady image.
The 18x50 IS binoculars feature a water-resistant, shock-resistant rubber coating for a nonslip grip and better durability. If you get caught in the rain and still want to view, you don't have to worry about the optics fogging up. These binoculars deliver high magnification and wide-field viewing. Controls for focusing and image stabilization are centrally located and accessible by both hands. These binoculars provide long eye relief for extra comfort.

Review of Canon 10x42 L Image Stabilization Waterproof Binoculars

Seems very expensive for a pair of binocs, but the price is clearly justified as Canon has crammed in some amazing optical wizardry in a small compact package. I will outline what makes these particular binocs so unique....

1.TFOV - 6.5 Degrees.TFOV = True Field of View - in visual optics this defines how much of the scene (subject) is visible inside the image circles you view through the binocs. The greater the TFOV is, the easier to locate subjects you are seeking. (such as finding wildlife that appears in the periphery part of the image circle) To be specific, the 6.5 degrees means, if you stood in the middle of a circle, and pointed the binocs to the circles circumference, you could see a 6.5 deg. "slice of the pie". It doesn't seem like much, because we can see approx. 110 degrees with our two unaided eyes, but the binocs offer 10x magnification, which is why we see such a small piece of the pie. But on a relative basis, for binoculars of this magnification, the 10x42L's TFOV is exceptional, which also is what makes them very nice astro binocs for stargazing, as TFOV allows you to pack more stars inside the image circle.


Large TFOV requires relatively short fl's lenses which must be well corrected for abberations / distortion, and also must contain large field stops in the EP's, (Eye Pieces). Both of these optical characteristics are very difficult to design and build...this is true in all optics, not just binoculars.6.5 deg. TFOV is one of the most generous TFOV's available in ANY binocs of this magnification, even those costing several thousand dollars.This is a very impressive feature.This is one of the features that differentiates lower priced binocs from higher priced binocs., as larger TFOV requires bigger (and heavier) glass.


2.AFOV - 65 Degrees. The "Apparent Field of View" is a clear and sharp 65 degrees. AFOV defines the size of the image circles you see when looking through the binocs. This means, at 65 degrees, your eye must swing 65 degrees, left to right (or up n down) to see the entire image circle. This has NOTHING to do with TFOV, which designates the how much of the subject (slice of the pie) you see in the AFOV image circles. AFOV and TFOV is what differentiates expensive optics from lower priced optics in the same class (such as 10x30, 10x40, etc) as large AFOV / TFOV requires very expensive and complex glass elements. The other major factor is image quality.


At 65 degrees, Canon is nearing the limits of AFOV, even in very high end astronomy gear.... and probably one of the largest AFOV's for any binocs I am aware of. But Canon maintained the sharpness in the entire AFOV, with virtually no distortion! (a remarkable accomplishment in optics in this price range) The larger the AFOV, the more life-like the view becomes as it fills your retina with imagery, ridding the "looking through a tunnel feeling" that smaller AFOV create. A single unaided human eye can see 90 degrees.So at 65 degrees, you are filling 2/3rds of your retina (where an image is formed in the back of your eye) compared to unaided vision. This produces a feeling of immersion (like Imax, vs. normal movie screen), and this really adds to the WOW factor. This is the largest AFOV I have ever seen in a pair of binocs at ANY magnification.This large AFOV is the first thing that will strike you when using these binocs. Unless you venture into high end astronomy gear (costing many times these binoculars) it's hard to find find good optics with a AFOV this wide, AND, with sharpness right to the edges AND virtually NO distortion.


3.L Glass....very sharp glass, with no false color and pinpoint sharpness, nearing true APO chromatic lenses. This is very evident when viewing stars at night, the stars are pin point sharp, better than most astronomy binocs I have used.... and with the the wide TFOV and large AFOV, you feel like you are space walking into the stars while laying back on a lounge chair.Of course, with only 42mm objectives, it helps to be in a very dark site. If astro use is the primary intended use, then larger objective diameters are better suited.50 - 70mm objectives are ideal, such as the 7x50's I mention below...or if you use a tripod, then max. objective diam becomes more desirable such as 15x80 or even 20x100. So, these binocs make good astronomy binocs, but not ideal...there is better options with bigger apertures for star gazzing... it's just a nice add-on feature if your intended use is mostly daytime viewing.

Those who use high end photographic lenses know how prized Canons "L" lenses are...hence why I was surprised to see "L" glass in these binocs.


4.IS - well, this has been beaten to death, but IS is the single biggest breakthrough since binocs were invented - assuming you want to hand-hold at high magnification. Otherwise, the IS feature is not as significant.The IS in these 10x42's are superb...the "push once" IS button is a nice feature, as you don't have to continuously hold down the button while viewing. The IS has a motion sensor which sense when viewing is finished, then shut down the IS, to save battery life - nice feature. But other Canon binocs have IS, so it's not what sets the 10x42's apart from the other Canon IS binocs...But if you hand-hold, and desire at least 10x or greater magnification, IS should be your single most desirable feature in binocs.


5.Aperture(Objective Diam.) -42mm obj. diam. at 10x magnification provides very bright views, specially during mid day, and good (but not great) at twilight. They are also "just" large enough to use as astro binoculars...once you begin star gazing through these you will become interested in the night sky. Buy a good binocular astronomy book and you will be amazed. If they tried to go bigger, the weight of the binocs would become unruly, creating arm fatigue, so I feel Canon reached a good compromise at 42mm objectives. A pair of UV filters are a good idea to protect the objectives as the elements are not recessed back far enough behind the rubber front rims.(one of the few shortcomings I have found with these binocs)I have a pair of Fuji 10x70's, which the 70mm objectives, which allow almost 3x more light in....yet with the IS and pinpoint sharpness, I am quite amazed how these Canons perform considering their small objectives for astronomy binocs. I am pretty sure Canon did not design these for astro binocs. But night time viewing is very acceptable with the 42mm objectives, as they allow 2x the light vs. normal 30mm objectives,and the added light is very apparent in addedsharpness and contrast.



6)Exit Pupil diam....The exit pupil diam of any visual optic, is the diameter of the circle of light that exits the eyepiece and funnels into (or on) the eye.The diameter of the exit pupil is determined by objective lens diam. / magnification. 42/10 = 4.2mm wide. The significance of this value is how it relates to the diameter opening of your eye pupil.If the exit pupil diameter is larger than your eye pupil opening, it means several things....


a)some of the light is being wasted, as its overflowing the bounds of your eye pupil opening. This wasted light means, you are carrying heavier binocs than you need to, as the weight and size of binocs are a function of the objective lens diam.(front lenses), at a given magnification.


b)However, this extra light, provides a useful benefit, as it allows some eye placement leeway, so you don't need to be so precise in setting the binocs IPD (Inter Pupilary Distance setting) and keeping the binocs dead still.As when the exit pupil of light misses your eye pupil opening, you get that annoying "black-out" condition in that eye.This happens very often when the exit pupil of the binocs equals your eye pupil diam.


c)The larger exit pupil diam. also allows your eyes to swivel a bit inside the image circle without the black-out condition. With these 10x42's, at 4.2mm exit pupil diam., assuming you set-up the binocs precisely, you have very little leeway to swivel (rotate) your eye inside the exit pupil diam., so this forces you to keep your eyes looking at the center of the image circles, and constantly move the binocs to keep the subject of interest centered. This can be quite annoying when watching a flock of birds...vs. having a large 7mm exit pupil, where you eyes can swivel around without moving the binocs.... but, you must carry larger objective lens binocs to gain this benefit. IMO, this issues is often overlooked in selecting binocs, and if compared side by side, it is obvious how luxurious large exit pupil diameters are. Hence why it sometimes makes sense to go for a lower magnification binoc. to gain larger exit pupil diameters.


To further complicate this matter, our eye opening dilates based on the amount of light hitting the eye. For mid day viewing, most human eyes are dilated down to 2-3mm opening, regardless of age.However, as we age, our max.eye pupil opening becomes smaller....this is very significant when selecting visual optics.Next time you get an eye exam, ask what the diam. of your dark adjusted pupil is. When we are young, our eye pupil will dilate open VERY wide at night. But age is very unfriendly to the eye in this regard.Here is an approx. chart showing how our max. pupil size becomes smaller through time...


Age vs. Eye Pupil Diam. (Avg)


Age ... Day light pupil... Night light pupil (mm)


20...(4.7)....(8.0)
30...(4.3)....(7.0)
40...(3.9)....(6.0)...Read more ›

Review of Canon 12x36 Image Stabilization II Binoculars w/Case, Neck Strap & Batteries

As an experienced brider (bird watcher to some) I've owned some of the world's greastest optics, the type of European "alpha-glass" that top tour leaders wear with pride.

I bought the Canon 12x36 almost 2 years ago based mostly on my respect for the Canon L lenses with internal stabilization that I use on a regular basis for bird photography.All I can say is... Wow!.These light-weight, high powered lenses have become my favorites in the field for wildlife observation, especially when viewing wild birds.

At first they took a little time to get used to.They really don't have the feel of a top-of-the-line pair of binos (they are somewhat darker than most and setting the eye-peices for your own interocular distance is a little strange compared to the roof prism glasses that many of us have become accustomed to), but they are what they are.These are not your daddy's binoculars.However, if you are looking for state-of-the-art high tech optics, look no further.

When a subject is focused you see the type of image shake that one would expect at 12x magnification.Then I depress that wonderful little button that activates the image stabilization feature. All of a sudden I feel as though I am now looking at the bird face to face, like I'm just THREE FEET AWAY!It's as if I was studying the bird in a book.I can see details and field marks that others only wish that they could.It has helped me to make some really tough indentifications for my life-list that I might not have recorded otherwise.

After being so pleased with the 12x I decided to buy the 18x50's.I've owned them both now for a while and I find that I take the 12x36's out much more often that the larger, heavier 18x. I highly recommend the Canon 12x36 for serious nature (and or sports) observation.

Product Description:
Amazon.com Product Description Canon's 12x36 Image Stabilization II binoculars incorporate an optical image stabilizer for shake-free viewing with minimal eye fatigue. This technology was first developed for Canon video camcorders and is now available in many of Canon's binoculars. The system employs a Vari-Angle Prism, dual transparent plates, independent vertical and horizontal sensors, and a dedicated microprocessor to continuously adjust the prism to maintain a steady image.
These 12x36 Image Stabilization II binoculars feature a water-resistant rubber coating for nonslip holding. If you get caught in light rain, you don't have to worry about the optics fogging up or getting ruined. These binoculars deliver high magnification, long eye relief, and wide-field viewing. Controls for focusing and image stabilization are centrally located and are accessible by both hands.
Improvements to the objective lens assembly have resulted in the binoculars being approximately 26% lighter and 10% smaller than the previous 12x36 IS model they replace. And reductions in power consumption mean a massive 270% increase in battery life of up to four hours using two AA-size alkaline batteries.
Image Stabilization and More
With any high magnification binoculars, most users will experience frustrating image shake. Unless fixed to a tripod, image shake can render high magnification binoculars useless. Canon's IS technology is remarkably effective at eliminating this problem and is widely used by the television industry with Canon's professional broadcast quality video recording equipment. A special VAP (Vari-Angle Prism) corrective IS system sits between the objective lens group and the porro prism on each side of the binoculars. Within thousandths of a second of the binoculars being moved from their optical axis by vibrations, a detection system activates the IS mechanism. The VAP shape alters to refract or 'bend' the light path by precisely the right amount, thus fully compensating for the vibration. It is this essentially immediate response that effectively suppresses image shake. The binoculars' compact design is based on Canon's popular 10x30 IS model. Curved surfaces mean easy handling, while nature lovers will appreciate the low-reflectance exterior and low gloss front covers, which help to avoid disturbing birds and other
What do the numbers mean?
15x50? 8x25? The two numbers used to describe any pair of binoculars are their magnification - 8x, 12x, 15x and so on - and the diameter of their objective lenses - 25mm, 36mm, 50mm, and so on. The larger the first number is, the larger the object will appear to be in the objective lens. For instance, if you use a 10x lens and look at an object that is 100 yards away, it appears to be the same size as an object located just 10 yards away. The second number, the size of the objective lens, is important because the larger the objective lens, the more light it can admit for brighter, more detailed images, and the better suited they will be for lowlight situations.

Review of Canon 15x50 Image Stabilization All Weather Binoculars w/Case, Neck Strap & Batteries

These binoculars are spectacular.Point them at Jupiter and you see a bright dot wandering around in the field of view.Press the image stabilization switch and the planet and its moons instantly become visible.While they can't subtract all movement they do get rid of the little shakes that make hand held viewing so difficult.15x is enough magnification that Saturn is obviously not round.
A complaint about earier versions of the Canon IS line was that your finger went to sleep holding the IS switch down.Now you can press it briefly to turn on the IS circuitry which will automatically shut off in 5 minutes.If you press and hold the switch it shuts off as soon as you release it.
I haven't had my pair long enough to comment on battery life but do see a problem changing them when they are mounted on a tripod.Unlike most binoculars where the tripod mounting is at the objective end where the two barrels rotate on the Canons it is at the bottom of the binocular near the center of the tubes which don't rotate.And the battery compartment is just in front of it so you can't get to it if the binoculars are on a tripod of have a quick release plate attached.
Since the lens barrels don't rotate intra-ocular distance is adjusted by actually moving the oculars.They are kind of stiff but that is good because they stay in place once you get them set.
The tripod mount is lower than the highest part of the lens barrels so if you have a big quick release plate like that of the Manfrotto (Bogen) 410 geared head (highly recommended) it presses against the bottom of the barrels and not the flat between them.
For some reason Canon doesn't seem to fell that the objective lenses need any protection as they don't ship lens covers for them.They do provide lens covers for the oculars but they pop off a lot because the eye cups are so soft.It looks like you need something like 69mm lens caps.They don't tell you in the manual but Canon sales says they are threaded to accept 58mm filters so you can buy solar filters for them.
I can use the binoculars with my glasses on due to the 15 mm eye relief but it is really easier to use them without the glasses.
They are heavy, ~2,5#, but if you support them on the heels of your hands very stable.

Super Spectra Coating
A number of optical factors affect the brightness of an image, including the amount of incidental light that is reflected by the lens. An uncoated lens will refelect away as much as 8% of the incidentail light, significantly dimming the image. Canon's Super Spectra Coating prevents that reflection.

Review of Canon 10x30 Image Stabilization Binoculars w/Case, Neck Strap & Batteries

If you want to get a quick idea why image stabilization (IS) is the next revolution in binoculars, that's easy: take any binoculars that you can get and look through them at some object (a printed page of paper with several font sizes is ideal). Then look again at the same object from the same distance, but this time with the binoculars moudnted on a steady support (don't touch em!). You will notice that the actual resolution increases by a factor of at least 2 or 3 when mounted. That is, you can discern details that are at least two or three times smaller, because mounting eliminates the smear caused by the shaking of your hands. IS is like having this support available any time and anywhere you need it by a push of a button! In most conditions, the practical resolutions I can get with my Canon IS cannot be matched by any hand-held, unstabilized binoculars in the market, including those fancy Nikons, Swarovskis, Leicas and Zeiss that cost three or four times as much. No matter how good (and how expensive) is the optics of these top-of-the-line binoculars, their limiting factor in the field is the shaking of your hands. You may have heard that IS is important because it eliminates eyestrain and headaches, or because you can use the binoculars from a boat or a moving car. While these are good reasons to buy the Canon, the best reason is that they let you see much more detail in any given distance. And this is the reason why you buy binoculars in the first place.
If you are a birder like me, and you are looking for a top of the line binoculars, do not buy anything before you try this one. In my opinion IS is going to revolutionize the whole field, so a costly pair of Swarovski or Zeiss, that normally could be considered as a good investment for life, will not be top of the line anymore in two or three years. In addition to the IS, the Canon has quite good optics, good field of view and is much smaller and lighter then most models you probably considered. This makes the Canon very close to the ideal birding binoculars: Highest resolution, less weight, and less money. I did not have the opportunity to test the larger Canon IS models, but I don't think I'd buy them even if I had the money, because they are twice as heavy and (very important for birding) has smaller field of view.
Note one general disadvantage of the Canon, however: They are not as tough as the top roof prism binoculars. They are water resistant but not water proof, and the IS requires batteries (a pair of NiMH for several hours of birding. This is the digital camera procedure: get a charger and at least one replacement set). While the binoculars feel sturdy, dropping them is not good for the IS mechanism, and this is probably why Canon gives only one year warranty. So the Canon are not the best pair to take for an expedition in Alaska, but for a Sunday birder like me, these are easily the best in their price range, and probably the best in any price.
