This exciting zoom lens provides ultra wide-angle coverage to the EOS 20D, 30D, 40D, 50D and Digital Rebel SLRs. Equivalent to a 16-35mm zoom, it offers excellent performance and optics designed from the ground-up for digital SLR use. Three Aspherical lens elements, plus a Super-UD element, assure image quality. Its ring-type USM means fast and silent AF along with full-time manual focus. It focuses as close as 9.5 inches.
Horrible Chromatic Abberration
I really do love the range of this lens and sharpness is pretty nice. I just cannot get over how horrible the chromatic aberration is. Even with advanced post-production it is still evident.

L type glass
I got this lens to capture lightning, and landscapes. And wow, it has done all of this and more, it is the sharpest lens I own, and I love the wide angle. It is a little exspensive for a non L lens, but is makes up for it in performance. The wide angle comes in handy when taking photos of unpredictable lightning. The close focus is also good for photos of flowers. All in all I am super happy with this lens.

Very nice lens
If you are shooting on a crop body in RAW, this is your wide angle lens. Not just for the obvious reason that it's the only EF-S, non-L series lens in the ultra-wide line up, but it is specifically designed to match the performance of a full frame with the 16-35mm L or 17-40mm L lenses. It's true! Compared to a full frame with an ultra-wide you get a similarly wide shot on a crop body, minimal distortion (warping), and a very compact and sturdy build for a dang good price. I know that for EF-S it seems expensive, but you'll feel differently after your first National Park tour with it.
There are, of course, some adjustments needed in processing. I typically set the chromatic aberration correction at -33 red/cyan in camera raw when I shoot at 10mm. The glow is obvious, especially in high contrast scenes but you can tone it down as you zoom in.
The quality of the shots and the build alone are worth the high price for this EF-S lens. The only reasons Canon isn't calling this an L series lens is the glass (obviously) and that it has "s" in the title. If Canon made an "EF-S L" lens, this would be it... again, with the L glass. The build quality, sharpness, focus speed, inner focusing system (that means "polarizer-friendly"), and the USM motor and focus depth window make this a steal!
For outdoor/landscape shots (mainly my thing) I rarely take this lens off my 7D and almost always shoot with it wide at 10mm. If you're going to use it with a flash you're internal will cast a shadow. You must, if you use a flash at all, use an external flash with this lens.
The optional hood seems silly when you first see it, but it's useful. If you go with the ball-cap-sun-shield you will almost always get a little sweatband/tattered brim in the shot... it's wicked-wide. The hood helps a great deal in most situations. The added bonus is that you won't bang your front element on all kids of stuff with the hood attached (which, if you're outside where you should be, then you'll probably do a great deal).
If you spend ANY time outside, can't stand changing lenses all the time, value... value, use a polarizer, and are at all savvy with shooting and editing RAW files... this, again, is your lens.
Buy it and enjoy.

Truly astonishing lens!!!
My every-day digital imaging requirements are better suited to APS-C format sensors ... but that doesn't mean I want to get locked out of the "normal" 17-28mm wide angle shooting opportunities ... Tried a Tokina 12-24mm AT-X several years ago and it was worthless, marshmallow-soft and chromatic edge-discoloured beyond correction. Enter a truly astonishing lens, the amazing EF-S 10-22mm!!! Not enough "w's" and "o's" in the alphabet to spell the number of "WOW's!" this incredble lens deserves! Yes, at 10mm, there's no mistaking this is anything short of an ultra-wide but the actual distortion is well-corrected and I can find absolutely minimal purple-fringe chromatic aberration - even when I pixel-peep. Thought it was a wee bit expensive for a lens w/o a red stripe on the front ... but it most certainly performs every bit like one!!! No questions here: TWO THUMBS UP!!! This lens is a treat to use and to a 1.6x factor body, a real "game changer"!!!
