A Praktica 50/2.8? Seeing as though it's only $15 I'm pretty tempted to pick it up, but is there anything I can do with it that I can't do with my 55/1.8? Does anyone have one? Does it possess any "special" bokeh capability?
I have never seen one that did not have a stuck aperture, ask the seller if he can get it closed. It does not have an A-M switch. You'd have to open it up anyway for the stuck aperture :-) The Takumar will smoke it anytime.
