 "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.

 "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.

 "A Fantastic Lens for the Price" 2010-01-10
By S. N. Mayfield (Eugene, OR USA)
I didn't buy this lens from Amazon but I do own it. It's a great telephoto lens and I've been really happy with the picture quality. My only gripe is that I wish it had a stabilizer. Even with that's only slightly dim, like that of a cloudy day for example, causes the photos to sometimes be blurred because the lens is long and heavy, so small movement can cause blurring. It isn't impossible to use without a tripod, though. It's an extremely good lens for the price, that's for sure. Overall I'm very satisfied with it!

 "Was free with the deal I did, but..." 2009-10-27
By Moo (Mad city, Wisconsin)
I got it free with my new camera, but I wish I sold it and bought a 55-250mm with IS or a 18-200mm with IS. They are much more expensive, but I hate having to remove it to put on a 18-55mm IS lens for indoor or closer range things. I can't complain too much since it was free. It's just that to fit in my camera case well this must be attached and in most cases I need to remove it and grab my other lens to take a picture. Not a bad lens, but you may get annoyed when you want to switch back and forth like me. Don't let this review deter you from buying it, I just had to put my two cents in.

 "It was good enough for me." 2009-10-27
By Daigo (Detroit, MI)
I have EOS Revel T1i, and very very beginner. That being said: I have 10-22mm ultra-wide, and 18-55mm standard zoom, and they are both fine, but I just wanted a lens that goes above 55mm.

So here it is. I do not have any complain about the picture quality so far, I just wanted to see what 300mm is like, and its definitely a different world, and I am happy to know that. USM is pretty nice too, so you may want to spend a few more bucks on it to get it. My standard zoom lens has standard motor and its slow and noisy. Anyway, I got what I expected, and again, I am happy.

 "High Quality Entry Level Lens" 2010-01-27
By silverram (Gainesville, FL)
I'm a serious amateur photographer who recently recieved the lens as a christmas present this year. I use it on my Digital Rebel XT and it seems to do a pretty good job as a entry-level zoom lens. I've been testing the lens out for about a month and I have essentially the same conclusions as everyone else: the autofocus is rather slow and clunky but I am still able to nail birds flying past me. The lens is rather slow at f/4 but I've taken some great shots at ISO 100 and ISO 200 by hand with it at 300 mm. I will say, I shoot in RAW and inspect all of my photographs at 100% zoom during processing, I can tell you that the optics of the produce a non-sharp image and tends to have chromatic abberation especially in high contrast regions. Even under the most ideal conditions at 250 mm, f/32 using a tripod, mirror lockup and the self timer with no filter, the picture is not sharp and I believe this is dispersion of the lens glass. I noticed the worst sharpening at 300mm wide open. However, the lens produces excellent contrast and the overall image quality is great. I love having the freedom to zoom in on distant objects. So it doesn't perform as well as a professional lense but as a amateur, I'm happy to have this zoom lens to complement my Rebel XT system.
