Evening everyone, I've been pondering adding another 80-200 zoom to my toolbox. I have three already, the f/4 and 4.5 and they are excellent. If I get another in this range I'd like it to be a 2.8 and manual focus for use on older film bodies, F2 and FE primarily. I found one on the KEH web site and was quite surprised at the cost, $619 in BGN condition. There were several AF versions at just over 1/3 of that. The MF lens has ED glass and internal focus but what could make it so high? At that price I'll probably skip it, already have an AF version of this lens and that would work but for these older bodies I'd prefer a manual focus lens. Ideas? Thanks. Rick H.
