The optical performance, fast f/2.8 speed and ultra-wide-angle coverage make this a great choice for many applications, like interiors, scenics, travel and photojournalism. It uses a "floating" optical system for excellent sharpness even at its minimum focusing distance of under 10 inches (0.25m), and with a ring-type USM and full-time manual focusing capability, offers the speed and handling pros expect.
Wide and Fast
If you need an ultra-wide angle and a large aperture, one of the following lenses will fit the bill. Ultra-wide-angle lenses can capture scenes beyond your natural field of vision. The EF 15mm f/2.8 Fisheye, the widest of them all, has a 180∞ angle of view. For more normal-looking wide-angle shots, there are longer wide-angle lenses up to 35mm with the maximum aperture you need.

On the 1.6x crop, the 20mm focal length looks like 32mm. I personally find that to be a wonderful focal length for general purpose use, and the f2.8 is acceptably fast for some indoor / low-light situations.
On full-frame, the lens is amazingly wide, and can be challenging to frame an interesting picture. Nevertheless, sometimes you need the lens to be that wide, so it's great to have. On the downside, the lens loses sharpness toward the edges, and is more evident on full-frame cameras than on 1.6 crop cameras.
This lack of sharpness is not always a big deal, as the edges of a photo are usually not the focal point.
I'm overall happy with it, and when I want wide, I usually grab my 20mm over my 17-40mm zoom.
But there is more going for this lens than sharpness. Distortions are VERY low for a lens of this focal length. You are NOT going to get anything nearly as good from a zoom. Also, color saturation and contrast are EXCELLENT - FAR better than, say, an EF-S 17-85mm lens. Colors REALLY come alive with this lens compared to most zooms. And chromatic aberrations are all but non-existant.
Construction also seems to be solid on my lens. The materials seem to be of good quality. The focus ring doesn't wobble much. And nothing external actually extends during focusing. This last fact is a REAL plus in outdoor environments, since an extending element creates low pressure in the lens (which can suck in dusty air).
I really have only two complaints about this lens. One it the price, which is somewhat on the high side. I personally got mine used for less. But $400+ is kind of alot to pay for a consumer grade lens. On the other hand, price is maybe not too bad, given the good overall quality of this lens. My other complaint is vignetting at large apertures. Simply put, vignetting is VERY noticeable at f/2.8 - even on an APS-C camera. I can only imagine how it might look on a full-frame camera.Read more ›
Drawbacks - A chunk of that price is for the 20mm optics of which we only see the central portion with a cropped sensor. The lens hood is extra. The lens diameter is 72mm so buying a polarizer lens will set you back.
Bottom line: I would give up my 85mm f1.8 and 50mm f1.4 - and maybe even my 35mm f2 - before I would part with this lens. Great for landscapes on cropped sensor cameras. People who have complained about this lens must have gotten a bad build.

- Can produce extremely sharp images from F/4+
- Build is decent, more solid than the 50mm 1.8
- Focus is fast and relatively quiet compared to zoom lenses
- Distortion (barrel primarily) is kept in check, better than most super-wides
- Color and contrast needs adjustment on most images
- As others have mentioned, images are soft around the edges
- Vignetting is VERY noticeable on full frame/film
- Seems to underexpose images (as also documented on The Digital Picture)
Here's the thing, this isn't an L series lens.Read more ›
