I read a lot of reviews about this lens before making a purchase of my own. The 2 things I liked the most about what I read were the claims that Canon appeared to be using "L" glass, or near-"L" glass in this lens, and of course the main feature of having an ultra-wide angle capability with a 1.6 APS-C camera like my EOS 50D. I can say now after some field testing that this lens gets a 5-out-of-5 stars on both of these accounts. Crisp focus and tack sharp images seem to be trivial to achieve with this quiet USM AF lens. I found the best 50D lens micro adjustment on my camera to be +3, but also found +0 to be quite acceptable, using the LCD monitor/moire pattern tuning technique at both ends of the zoom range. What REALLY tooted my horn however was the new found capability to take shots that were simply not achieveable before with my 28mm lens. Whole rooms in the house became one-shot deals, as opposed to the cumbersome image stitching technique. Groups of people near by - no problem getting them all into 1 shot. Landscape challenges - a snap without having to back up and up some more, and still wind up stitching multiple images together. Of course, everything written about straight-line distortion at the 10mm end of the zoom is true, but not to an excess, and in my opinion is MORE than offset by the capability to simply "get the shot all at once". An indoor 6 story atrium that previously took 6 stitched photo's to capture - now easily captured in 1 shot. Focus was achieveable at a tiny bit over 4" from the front of the lens. No IS on this lens, which I missed while trying some low-light shots (I kept waiting for IS to kick in out of habit, since all my other lenses are blessed with this feature), but this is only a concern on extreme close-up's, which is not generally what you'd use this lens for anyway. The lens has an AF/MF switch of course, and is only usable on certain camera's that are compatible with EF-S type lenses (there is tons of online info about that to be read elsewhere). The filter size is 77mm. There is a light hood available from Canon, which I don't own yet, and I've read that it's marginally beneficial for blocking light since it's so small in order to accomodate wide angle zooming without getting in the way. I'll still buy one and put it on for extra front-end lens protection at around $14. It's easy to bump in to things and a lens hood makes a lot of sense for that reason alone. Anyone who's ever bent the metal of a filter after lightly bumping in to something, and then struggled with filter removal, lens cap fitting, etc., will know just what I mean. I took some test shots with the built-in flash, and the 10-22mm lens does block the lower 5-10% portion of the picture at wider angle zooms. I was able to compensate for this in most shots by pointing the camera downward a bit more. Still, I'd recommend an external flash when using this lens, to take care of this interference and of course to get far superior bounce flash shots. There was no issue with the lens blocking any output from a camera mounted EX flash. No lens creep on this lens. The overall lens length does not change with zooming. The zoom ring is snug, but turns smoothly, as does the focus ring, which can be turned after AF'ing for any fine tuning of the focus. The subject end of the lens does NOT TURN when zooming, which is great for circular polarizers and other filters that need to stay oriented. The lens length is 4" (with a UV filter attached) from the front of the lens to the camera body face. At first I thought this lens might be a specialty lens that I would only use when I needed whole room shots or was met with other wide angle challenges, but with an effective 35mm range on an APS-C camera, the quality of this glass makes it a candidate for a lot more uses as well, enabling quick access with a twist of the zoom ring to any action that comes in "close", or to capture 2 subjects that are not conveniently side-by-side, as is sometimes the case with candid photo's. I have to admit that I'm writing this review after taking less than 300 photo's with this lens, but the image quality and jaw dropping access to amazingly wide "views" that I've never had the ability to capture in one shot with a dSLR compelled me to brag "now" about this lens. If I encounter anything noteworthy after taking some more test shots under various conditions, I'll amend this post. In all honesty, it's hard to imagine anyone who has ever been challenged by a wide angle shot not immediately falling in love with this gem once they get in to the field with it. Five star thumbs up on this one. Canon EF-S 10-22mm f/3.5-4.5 USM SLR Lens for EOS Digital SLRs

I bought this as a birthday gift for my husband, because he had requested it. I have never been much interested in wide-angle lenses--to me, long telephotos were the ones I lusted for. This lens has changed my mind. It opens up new worlds of photos that I had never thought about! The quality seems great, as usual with Canon lenses. It's small and relatively lightweight. The pictures look good to me--I don't have the chops to evaluate them in a technical way, but the color rendition and sharpness look good.

My main use of this lens is to create landscape panoramas, usually with a tripod in day light, but often to get a lot of scene when going back is not an option. I find the optical quality good, and I get good colors & contrast with it, with depth of field I find impressive. Standing close to a cliff's edge, I can get both near by stones & plants and far clouds in focus. The auto focus is quick & accurate, this probably being the only lens that never fails to autofocus, whether on people from close range or on landscape far away. People who hold the lens often comment about it being lightweight, e.g. it is lighter than the EF-S 17-85mm I use as a kit lens on my Canon 450D. Bottom line, I don't see myself departing with this lens till that far-away day when I can upgrade to Canon 5D & EF 16-35mm f/2.8L lens.
