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.
Wonderful ultra wide angle EF-S lens
I use the 10-22mm f/3.5-4.5 USM mainly for waterfalls and small cascades in the mountains of the south east US. With a APS-C camera sensor this focal length is superb. While there is some distortion at the 10mm end for my purposes it is not objectionable. However, there is a fair amount of chromatic aberration. The lens produces fairly sharp images. The corners are less sharp. However, at this scale of image size details are small and it is not objectionable. The lens is not overly heavy, but it does have a nice quality feel and weight to it. The focus ring is nicely balanced, not too stiff nor too loose.
I would have rated the lens higher for Features, but it does not come with a lens hood, and should.
I would like to rate the quality higher, but the lens is not weather sealed. For my shooting near water spray, this would be great.
However, the quality of the images, the size of the lens, and the price make this lens an excellent product.

O.K., I was already blown away with the quality of the lens itself and with the pictures I took with it, but nothing compares to what happened to the lens over the winter. I was out shooting some nature shots here in Central Ohio where there was quite a bit of snow on the ground; somehow the lens fell out of my bag and I didn't realize it until I got back to my car. I retraced my steps all to no avail. I notified the park ranger that I had lost the lens and, still having the lens booklet in my bag, was able to give him the lens information. Well, 3 months later I get a call from the ranger. Yes, they had found my lens! Although I was happy to get it back I knew it couldn't possibly be functional after 3 months buried in the snow. I was wrong. Not only was it functional, but the picture quality was diminished in no way! No fogging, no condensation, nothing; it just works. This is just one of the reasons why I have never owned any camera or camera accessory other than a Canon!

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.
