Last year I had a chance to handle the 50 f2.8 at a dealer. Aside from 2.8, I didn't like it, heavy & bulky, a fish-eye type front element that requires extra care from accidental damage (of course, use a hood also). Only reason to buy this lens I can figure, is you need the speed. See if you can try before you buy, it's one of the heavy Schneider's.
