Your 35RF (goggle) and 50 DR Summicron will work and focus just fine on any M Leica The RF goggles on 35mm lenses just change the angle of view of the 50mm field on an M3 to show the coverage of a 35mm lens The Goggles on a DR Summicron depress a pin on the top of the mount and allow you to adjust the lens to focus as close as 19" While I do not have a TTL M6, the RF CAM (the wheel at the top of the lens mount) follows the lens to 19" just fine on my M2 M3SS M4 M4-2 M5 and NON TTL M6. There is one other CAM on M lenses. This is the CAM that "tells" the camera what the focal length is and brings the proper frames up in the finder. A few early non RF 35mm Summarons (from 1954-55 quite rare and probably collectors pieces) brought up only the 50mm frame (there was no 35mm frame to bring up) making it necessary to use a 35mm finder...and, of course because the RF 35mm lenses modified the 50mm field of view to make the field of view for a 35mm lens this is the frame that is up (of course with an M3 this is the frame that is always up anyhow). The M2 and later models (except perhaps the M6J) solved this... Thanks Mark - -- To unsubscribe, see http://mejac.palo-alto.ca.us/leica-users/unsub.html
