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: This is a very useful lens wide angle lens for a full frame camera if you're on a budget or need to pack light. If you're looking for ultimate image quality, click elsewhere. If you want a cheap 20mm lens that is reasonably well built and gives good image quality at f/5.6 or f/8, this may be what you're looking for. On a APS-C camera, there are plenty of better options than this.
Pros: Small, light, inexpensive, fast silent ring USM, good build quality
Cons: contrast a little weak wide open, hood is huge and probably useless
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.
