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: awesome wide-angle lens for its price. although the product has been discontinued by canon, it still offers fantastic image capabilities and have been my favorite so far when taking landscape photographs. its quick to focus,and quiet with the USM. the manual focus override is ideal for night photography. i don't notice any vignetting at its widest focal length which is fairly common for wide-angle lenses. no barrel distortion either.
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
