Not Great, but better than the alternatives.
Date: June 25, 2009
Pros: inexpensive for this focal length
Cons: poor corner quality
Vignettes badly at f2.8 and f4.
Corners not sharp at all at f2.8 and f4.
Good central sharpness at f4, f5.6 and f8.
Corners ok at f5.6, slightly better at f8.
Nice modeling effect and bokeh quality at f5.6 and f8.
Looks worse at f11 and smaller stops - diffraction?
Distortion is much less than any of the zoom alternatives.
Color rendition and contrast are good at f5.6 and f8.
Not a good reputation, so very inexpensive second-hand.
For extreme-wa shots at f5.6 or f8 it does the job, better to have than have not.

this is a good lens. i first got the lens over four years ago. i've taken it with me everywhere, and am always happy with the image quality.
however, it has slow auto-focus (an issue many canon lenses seem to have)

Unsharp at any f/stop
Date: March 25, 2009
Very poor image quality, this lens is a dog. Lens sharpness fall-off at the edges is awful. This lens is always left behind.
