Customer Reviews

Although a little pricey this lens has exceeded my expectations. It takes beautiful pictures and anyone who has a xsi should think about purchasing one.

Great lens, but....
I purchased this lens as my second lens for my 40D, which came with the solid all-around 28-135mm IS USM lens. I read the reviews, and the verdict was not so great for the 10-20mm Sigma that runs $200 less -- most said it was worth spending the extra $200 for the Canon. One blog review suggested this as a nice 2nd lens to compliment the 28-135.

After about 300 photos with it on 2 recent outings, I can attest that this is a very good lens. Sharp autofocus. Great color.

But....as others have noticed, you're somewhat limited in the 10-15mm range due to the distortion. That makes the functional range typically between 16mm and 22mm. No complaints in that range, but I'm starting to wonder if the EF 17-40mm "L" lens for the same cost would have been a better lens. For most general photography 17mm is wide enough, and having the option to lengthen out to 40mm will mean less swapping of lenses for general photography.

Or you could pony up an extra $300 and bump up to the best EF-S lens made, the 17-55mm f/2.8 IS USM....which give you image stabilization and a more indoor-friendly aperture for shooting indoor minus the flash.

So understand what you are getting with this lens. It can definitely do wide angle. However, many amateurs may find the 10-15mm range not all that necessary. In which case, your money might be better spent on the 17-40mm L lens.

Excellent
I am really enjoying the Canon 10-22 Lens.

I purchased this about 8 months or so ago to add to my lens collection and to try to improve on the imagges from the Kit Lens. Though the Kit Lens is okay, the other lenses in Canon's collection do perform better. (I also have the 60mm prime lens.)

Though this lens is slightly more expensive than some of the other brands, I have had very pleasent experiences with Canon products.

The color and resolution of the 10-22mm is superb, though at full wide angle there is some slight distortion/strange affects which is pretty much to be expected in Wide Angle lenses, especiallly non-prime ones. 12mm or so and up and I reallly like how it works. Opens up new possibilties of shooting if you have not used a wide angle before.

One thing to note is that this is not for a full frame sensor camera (though if you own a full frame you are probably aware of this.)
