I have a Horseman 45 FA and am looking for a used tele lens in the 300mm range. My camera is limited in that the hole in the front standard is around 63mm dia., and the lens boards are small (80x80 mm). Bellows is limited to 10 or so inches.

I have some lenses (75, 90,180) in copal "0" and Copal "1" already mounted.

I don't know if they make a board that excepts anything bigger.

So I'm looking for a 300 or so tele that will mount in a "0" or "1" board, or bigger if Horseman makes one.

Does any know what tele lenses I should watch for on the auction sites that will fit.

Thanks, dee
