Canon EF-S 10-22mm f/3.5-4.5 USM Review
05/27/2006

For landscape, indoor photography, or situations where you can't back up enough to capture a scene, a super wide angle lens, such as Canon's EF-S 10-22mm f/3.5-4.5 USM, may be just what you need.

Canon's EF-S 10-22mm f/3.5-4.5 USM includes 3 Aspherical lens elements and a Super-UD element in it's 13 lens elements, 10 groups construction, which probably explains the high cost of this lens (relatively speaking of course). It uses a 77mm filter which adds to the cost. The focal length of 10-22mm is equivalent to 16-35mm on a full frame sensor and if I had a camera with a full frame sensor, I would probably get the 16-35mm lens at double the investment.

Note that the "S" in the EF-S stands for "short back focus" and will only fit on cameras with APS-C size sensors such as the Digital Rebel XT.

You'll have to excuse my reviews on Canon's EF-S 10-22mm f/3.5-4.5 USM because my comments are based on using the EF-S 17-85mm f/4-5.6 IS USM as a reference.

Canon's EF-S 10-22mm f/3.5-4.5 USM is about the same size as the EF-S 17-85mm f/4-5.6 IS USM but lighter by 3.2 oz. Probably because the 10-22mm has 4 fewer elements than the 17-85mm and it doesn't have IS (image stabilization). It is slightly lighter in weight than a can of soda by about 1/2 oz.

The first thing I noticed was the quality of construction. It is very good and solid for a plastic body. There is no slop in the zoom or focus rings and both rings rotate very smooth. What is amazing about the EF-S 10-22mm f/3.5-4.5 USM is that rotating both rings does not affect the length of the lens. Why can't all lens be made this way?

Using Canon's EF-S 10-22mm f/3.5-4.5 USM
The lens has a single switch for auto/manual focus and when in autofocus, the motor is nearly silent, and the focus is almost instant. The EF-S 10-22mm f/3.5-4.5 USM rarely misses focus because, at wide angle, there is so much detail compressed in the scene.

My concerns here is the lack of image stabilization and consumption of coffee. I found out that by hand holding the camera, I can take clear pictures at shutter speeds down to 1/30 sec with no evidence of camera shake, but anything longer that, it becomes a hit-or-miss. I've taken some good pictures at 1/5 sec exposures by bracing my arms against a wall or chair and I've been successful at 1 sec exposures using the monopod. Compare to the EF-S 17-85mm with image stabilization, at 17mm, I can get clear pictures at 1/10 sec exposures.

There is no wobble in the lens elements while zooming and focusing (manually) and both rings are fairly well damped, meaning that there is a slight resistance when manually rotating the rings.

At 10mm the angle of view is simply breathtaking. There's a slight barrel distortion at 10mm which disappears at around 14mm and, there is suppose to be a very slight pincushion at 22mm. Visually the pincushion isn't noticeable until you show the Grid in Photoshop and even then, it is very slight.

I've read reports that, at 10mm, the EF-S 10-22mm f/3.5-4.5 USM will exhibit some vignetting. But in my case, I found that not to be entirely true. Even with or without the filter on the lens, there is a slight evidence of vignetting at f/3.5 which goes away at f/4.5.

All the photographs above have been taken in jpeg mode, and reduced 50% in Photoshop with moderate jpeg compression to conserve disk space and bandwidth. Camera was handheld using autofocus (unless otherwise noted). No color corrections, level adjustments, sharpening or croppings were made.

Conclusion
Canon's EF-S 10-22mm f/3.5-4.5 USM is a solid, impressively built lens. It's wide depth of field allows objects/subjects to be clearly in focus from a few feet away to infinity. The pictures are very sharp from corner to corner and, with minimal distortions, it is perfectly suited for architectural photography.

I soon learned that this lens is not the type for all around shooting. You are limited to super-wide to wide angles, so portrait shots are definitely out of the question (although I have done some, with interesting results - it's the amateur in me). For me, it is not a "must have" lens but, in certain situations, it does come in handy. If you're and architectural and/or landscape photographer or, you are constantly shooting in situations where you need to capture as much of a scenery as possible in a photograph, then, the EF-S 10-22mm f/3.5-4.5 USM may be the "must have" lens for you.

My one wish is that this lens had IS (image stabilization).

My second wish is that the rest of my Canon lenses were constructed with the same solid, quality build as this one.
