Canon EF-S 10-22mm f/3.5-4.5 USM SLR Lens for EOS Digital SLRs

Canon EF-S 10-22mm f/3.5-4.5 USM SLR Lens for EOS Digital SLRs – Product Description:

Canon EF-S 10-22mmWith its effective focal length range of approximately 16-35mm in 35mm format, the EF-S 10-22mm f/3. 5-4. 5 USM is a remarkable lens with outstanding image quality that will take your photography into new dimensions and areas of dramatic expression. The super-wide zoom not only gives you the freedom to get exactly what you want in the shot, it dramatically alters perspective to allow for dynamic expression. The lens allows you to get extremely close to subjects, exaggerating the difference in size between a near object and its background. Creative photographers can use this phenomenon to create excellent separation between subject and background for a strong sense of presence, or for a pan-focus effect with everything from foreground to background sharply in focus. Exceptionally light and compact for its focal length range, the EF-S 10-22mm f/3. 5-4. 5 USM also has an incredibly close minimum focusing distance of just 24cm. A ring-type USM works in concert with the camera to provide super-fast, precision auto focusing and predictive tracking – with full manual override available at any time. Designed specifically for digital photography, the lens has specially shaped lens elements and Super Spectra coatings to suppress ghosting and flare, which can be caused by reflections off digital camera sensors. An exclusive optional lens hood can further reduce the incidence of flare. A circular aperture provides a pleasing background blur when shooting with a wide aperture; ideal for creating a sense of depth and getting your subject or model to stand out from the background.

Canon EF-S 10-22mm f/3.5-4.5 USM SLR Lens for EOS Digital SLRs- Review:


I have had this lens for several months now and let me start out by saying WOW. I looked at the lens in the store along with the Sigma 12-24 and I was in total awe of what I saw though the view finder with the Canon 10-22. This is an ultra wide angle lens that is incredible. I went home and thought about where I would use this lens and determined that I would use it quite a bit. I went ahead and bought the lens and I continue to be more impressed with it every time I use it. I have used the lens for both close-up (which can give you some very interesting distortion shots)and wide angle shots with great success.

The 10-22mm is equivalent to 16-35mm field of view using a canon 20D which is not a full frame sensor. With a minimum focal distance of .24m (about 9.5 inches) you can get very close to objects and still get alot of focal width in the photo. There is incredible clarity in the lens. The photos I have taken are very clear with only a slight hint of softening at the corners at 10mm; everything else is sharp after that. There is a little barrel distortion at 10mm but everything else up to 22mm is nice. I have not gotten any light flare in my photos. The Ultrasonic motor is very quiet. The depth of field is outstanding. A slim UV filter helps prevent some slight vignetting at 10mm. With a maximum aperture that ranges from f/3.5 to f/4.5, the Canon EF-S 10-22mm f/3.5-4.5 USM Lens is a medium speed lens. I would recommend using a tripod if you are at all unsure about your ability to hold the camera still for action shots with this lens. The lens it’s self is fairly light weight. If you are going to use filters the lens requires 77mm.

The lens can produce some interesting distortion shots if you are taking close-ups and are not perpendicular to the object. For close-up shots with out distortion it is best to be perpendicular to the object.

Inside the lens housing there are three aspherical lens elements and a Super UD element that produce clear vibrant shots. The lens it’s self sturdily built and comfortable to handle.

UPDATE 7/30/2011: I still love this lens. It functions every bit as well as it did the day I got it.
