I've had two of the 35mm l lenses, and both were supurb. Its amazing how someone can pronounce it as not so good, and never own or even use it. Of course it can be better, but its already supurb.
I was stuck without the proper lens in a low light arena shooting my friend's monster truck. Mo problem, just put on the 35mm L and crop to 100%. Prints are beautiful.
Thats him, clear accross the arena.
