Wow, this forum is amazing! Such helpful people. I wish I would have been shooting alt gear years ago!
Anyways, I hear you guys about the BIN button, especially with bing.com ending. I am awaiting like $95 back from recent purchases. I think I will go with the 80 2,8. I would like the 80 4,0, but I don't shoot Macro (would like to, but realistically I would shoot portraits 90 times more).
I think I will try to pick up a 55, 50 or 58mm in some sort of mount that I already have an adapter for.
