Great lens for the price. Gives a very sharp image.

Summary: Overall, this is a very good lens that every filmmaker should have in his bag. Yes, I use my DSLR primarily for filmmaking and have found the 20mm focal length to come in handy a lot of times. Very sharp image given its price point. Definitely a good lens to have in the bag!
Summary: The lens history is that it was developed for production in 1993 for SLR’s. It was noted to be popular lens in its heyday but is discontinued. There are still parts available to fix the les if required. However Canon’s continual approach for upward compatibility made it a good lens for DSLR as well. I bought this lens because I wanted a day-to-day type of lens. I found that this lens does fit my Canon EOS T2i (550D) like a charm in the APS-C format.
Summary: I needed a wide angle lens for my Full Frame Canon 5D and after owning the Canon 28-105mm f3.5/4.5 which I hold in very high esteem, I figured this would be a good match for travel. Like I expected the lens is compact and very light. It is not as sharp as any of my 'L' series lenses, or even as sharp as my canon 10-22mm Super wide angle lens, but sharp enough. Unfortunately I can't use the 10-22mm crop sensor lens on a full frame camera like my 5D.
fast focus, ligh and cheap enough to take snowboarding.

Summary: Comparing to old 17-40, just as fast focus, decently sharp, and found use for my old 77 skylight. Had heart set on 20 2.8, but for the price couldn't pass this up. Mostly shoot board sports, also mechanical photography.
Conclusion: In today's world of rotating front lens elements, plastic lens mounts, buzzy-cheap micro-motor focusing and overall kit lens quality products.....what a refreshing thing to pick this lens up and feel some actual build quality in an inexpensive lens! USM focusing motor (which the holy L version of this lens does NOT have) is wonderful. Quiet, accurate focusing with a distance scale as needed. Internal focusing so you can use all types of filters with no problems.
Pros: Build Quality USM Motor - Full Time Manual Override Internal Focusing Distance Scale Sharpness
Cons: Huge Lens Hood Not Much Zoom Range Not Super Wide
Conclusion: I just bought this little lens off ebay for a great price. I have noticed so poor reviews here but at the price I thought I would give it a try. Some of the observations made by others are quite correct and I found from my initial test that the images tend to lack a little contrast straight from the camera but IMO nothing that can't be easily adjust in PP. The images I have taken appear sharp, not world class, but again for the price very good.
Pros: Lightweight, quick and accurate USM focusing, price.
Cons: Images a little flat and lacking in contrast but easily trewwkable in PS
Conclusion: A used version of this lens sat for a number of months at a local camera shop. I was itching for a wide and couldn't disagree with its very low price, even for a used wide zoom. Even though it's range is limited by today's new lens offerings, it does fit a niche. The keys to this lens, really, are its low used price, its size and weight. Some CA at 20mm, softish corners even on a crop. Manageable, but something to consider. I actually like this lens.
Pros: Affordable as candy on the used market; very light; compact; durable for its cost;
Cons: Soft in corners; CA a bit esp. at 20mm; most of its results need post boosting to sharpening, color, contrast
Summary: I purchased this lens about a month ago, It really produces good images, although you will get a shadow cast on the pictures when using the built in flash, so always make sure to use a shoe mount flash/studio lighting. I use the Canon 40D and also the Canon XT350, I would probably prefer the 10-22mm for a wide angle lens, although for the difference in cost it is well worth it. Make sure to also buy the pedal hood for it though!
Summary: This is a delightful lens. It is exceptionally compact,light-weight, versatile (for wide-angle shooters), and at anexcellent price! I've used it for about 5 years as myprimary lens -- the past two on my 5D (making for anawesomely powerful, non-cumbersome documentary unit). Itsoptics are flawless. My only complaint is the manual focusring; but that is ALWAYS my only complaint with Canon zoomlenses: their focus rings are horrible little things.
