There are ways around it, like the system used on the Dual-Range Summicron, and some other RF lenses have been made that focus closer, but without rangefinder coupling at the closest distances. I didn't know the Mamiya 6/7 could only focus to 6 feet. I think that's just the 150mm lens, the other lenses focused to 3 feet. -- Chris Crawford Fine Art Photography Fort Wayne, Indiana 260-437-8990 http://www.chriscrawfordphoto.com My portfolio http://blog.chriscrawfordphoto.com My latest work! http://www.facebook.com/pages/Christopher-Crawford/48229272798 Become a fan on Facebook On 12/16/12 6:50 PM, "Richard Man" <richard at richardmanphoto.com> wrote: >Idle wonder time: what limits the close focusing range of a rangefinder, >as >comparing to SLR lens?
