I have a Promaster MC Zoom 1:3.8 f = 80~205 mm 55 No. 837565 Auto, Zoom lens for sale with carrying bag. I don't pretend to know any thing about cameras. the only thing I do know is it won't fit my wifes 35 mm Canon. The man I got it from showed me how good it worked on his camera. It's in excellent shape. $25.00 obo or possible trade of comparable priced item.
