+1 on the Yashinon lenses, particularly the DX 50/1.7, which is superb. I really haven't tried near enough lenses other than 50mm to form an opinion on them, but other favorite 50's include the Pentacon 50/1.8, the Nikon "E" 50/1.8, and the very common and dime a dozen Canon FD 50/1.8, there is a reason that they sold millions of them. A real sleeper is the Yashica ML 50/2, it is a little gem.
