 "Great Lens for low light and fast" 2010-01-12
By Risch (Orlando FL)
I use this on my 40D, was not impressed with the previous reviews but needed a 20mm so went ahead and pushed the button. Picture quality was stunning at the amazingly low lights and the lens was super fast. excellent built quality. A great buy for an ultra wide angle.

 "bad lens" 2009-08-12
By Otto Haring (Miami)
I used it to shoot from an elevated angle. The result were disappointing.....I paid $[...] but I don't think it is even worth more than $[...] to tell you the truth.

The colors are lifeless, "burnt-out". There are no details on the images. You can see the samples on my site: [...] Look for the huge house with the red roof. You will see what I am talking about. Normally, I use the 17-40 L on my elevated system. I thoguht the 20mm would be a good replacement even if it not as good as the 17 40. I think even the 18-55 Canon kit lens produces better images. Add a few hundred bucks and buy a decent lens.

Always happy with Canon Lenses.. I am more a detailed photographer, I purchased this mainly for my husband. He enjoys taking more landscape photography. Overall, very happy!

 "Great, versitile lens" 2008-07-14
By John Koehn (Arlington, VA)
I was a bit concerned at first with the fixed focal length, but it has proven to be very versatile. It takes very sharp pictures, even when fully opened in low light. I have not noticed any of the vignetting that other users have mentioned.



Bottom line: great wide angle lens for the price. Useful for landscapes and tight space, low light situations.

 "disappointing, especially for a fixed lens" 2008-03-03
By Neurasthenic (New York City, New York)
This is one of the first two lenses I bought when I switched to a Canon SLR about five years ago. I've had plenty of opportunity to use it since then, both with film and (full frame) digital.



The idea behind this lens is a good one -- 20mm is wide enough to allow for landscape and architectural photos, and it focuses close enough for entertaining photos of people's faces, taken about a foot away from their noses (note that you'll need either a ring light or lucky ambient light to pull off the latter). There is some pincushion distortion, but nobody would accuse the results of looking like a funhouse mirror, as would be the case with a fisheye lens, for example.



f2.8 is fast enough; I've no complaints there. Unfortunately, this camera consistently vignettes -- the corners of every image are dim. This is true even with a bare lens, and filters make it worse. You can correct the problem in image editing software, or just crop the image, but what's the point of buying a 20mm lens if you're going to have to crop every photo you take with it?



If this had been a cheap zoom lens, I'd have expected the problem and not been bothered by it. With a fixed lens, however, I think there isn't much excuse.



Canon still charges about the same ($400) that I paid for this lens years ago. By now, they ought to have upgraded this thing, or dropped the price. It is the worst EF lens I own.





-- addendum: I've recently been using a Canon EOS IX, which takes APS film. This lens is much more useful with that camera, though using even APS-H, you get something akin to the image you would get from a 35mm lens on a 35mm negative.
