The Sigma 20mm f/1.8 DG for Canon

The Sigma 20mm f/1.8 is unique in being a wide-aperture 20mm prime lens for full-frame cameras. Sigma markets it as excellent for landscape photographers because of its excellent optical performance, but it's better known as a wide-angle lens for emphasizing center subjects. It can focus as close as seven inches, which allows for some interesting "wide-angle pseudomacro" shots.

Roger's Take

This is a rather controversial lens. On the positive side, it has a very wide aperture, which is rather unique for a wide angle lens. The lens is large in size for a wide-angle prime, especially in diameter (note the 82mm filters). When wide open at f/1.8, it’s quite soft except at the center; this setting is best used for "special effects." When stopped down to f/2.4 or so, it is very sharp in the center, but the edges never really sharpen up. There have been reports that it has trouble autofocusing in low light, but since anything more than a few feet away is "infinity" at this focal length, manual focus is quite easy.
