Several others have suggested filing off an offending pin to prevent the lens getting stuck on the camera. Could you post a photo of the lens flange and the pin in question? I'd be interested in seeing it. BTW: This *is* a dynamite lens! >As for the A/P setting, according to Mark's site, which JCO pointed me to, >the lens was made in either 75 or 85.

Well there was no such thing as an "A" setting before 1982, so that pretty much wraps up the date question :) -- Mark Roberts Photography and writing www.robertstech.com
