Thanks for the quick reply folks. Right now, it's sitting at $250.00 with 5 days to go. This lens has been going for $400-500.00 on average from what I can see. It's getting close to what I figure I want to pay for a lens with stuck aperture blades. There are a few youtube repair videos floating around, and as you say Andrew, it's seems to be an easy disassemble. If I can clean the blades then great..if not, 1.2 it is. Guess I'll wait till we get closer to the final hours of this auction ... In the meantime I'll visit your recommended site Silent..Thanks again all.
You don't know it's oil on the blades. You won't know anything about it until you have it disassembled and diagnosed. You are truly buying a pig in a poke.
