mervyn_wilmington Posted February 12, 2015 Share Posted February 12, 2015 <p>According to Mamiya, it is to be preferred that this ring is used when a 'c' lens is fitted to an RBSD body. However, it seems that many people do this without the ring: it is for light saving purposes, not mechanical.</p> <p>Moreover, the rings seem to be few and far between. I wondered about trying to make one, possibly out of foam rubber. An illustration suggests they are rebated. Is that right, and might a member have the specifications of the ring, ie the inner and outer diameters and the thickness?</p> <p>Help would be appreciated.</p> Link to comment Share on other sites More sharing options...

mervyn_wilmington Posted February 13, 2015 Author Share Posted February 13, 2015 <p>Many thanks Jim. I've actually spotted two 'genuine' Mamiya rings, but at £20 and £25 respectively, they are not cheap!</p> Link to comment Share on other sites More sharing options...
