What Eric is describing is a 3rd-cam lens. Some 3rd-cam lenses have an R-only bayonet and some have a Leicaflex bayonet. For example the 50mm Summicron-R I used to have was originally a 3rd-cam lens and was marked "FOR LEICA-R ONLY". It had a Leicaflex bayonet and all it needed to be turned into a 3-cam lens was the first and 2nd cams. It even had the screw holes for mounting the Leicaflex metering cams. OTOH my 280mm f/4 APO-Telyt also was originally a 3rd-cam lens with an R-only bayonet. In addition to the cams the 280 needed either a replacement bayonet flange or some machine work on the R-only flange. - -- To unsubscribe, see http://mejac.palo-alto.ca.us/leica-users/unsub.html
