i'm sure there are variable at play here that have to be considered but since we are talking about the ziess 21mm f2.8 i for one would look pretty hard at the canon 24mm 1.4. is photozone biased? look at the resolution charts for the ziess and canon next to each other. they are full of praise for the ziess, and call the canon's performance a rollercoaster. well, i don't know what numbers they are looking at because their numbers show canon is better than the ziess everywhere, then drops off as the aperture is opened to amounts the ziess can't even reach. perhaps canon shouldn't have permitted this lens to open wider than f2.8, then it would have gotten better press. add autofocus, weather seals, and a 77mm filter size and it's really looking good.
