I used to shoot SLR's of the variety that is to remain unnamed... It isn't film.....
The 70-210 f/4's iris doesn't stop down if I push in the DOF preview (slide? Is that the word for it) that sits toward the bottom and right of the lens. I had managed to get it to 5.6, open it up again, and no luck any longer. I assume this means the blades are oily, if my research is correct.
The 50mm (well, both of them) is the Canon FD that came with the AE-1s, and the 135 is a Sears. Allegedly the Ricoh rebadged variety, but the proof will be in the pudding. Just wanted to see if I got a fair price, at least. Not worried about every penny but it feels good to know you got a square deal.
