I once tried using a 70's vintage Nikon (lens flange) to T-mount adapter that I acquired from an old Soligor, multi-mount bellows (used T-mounts, both front and rear. I mounted it on the Nikon lens and installed a Leica R, T-mount on it and mounted all of it on a R4Sp body. Worked great. I regularly use an adapter that I acquired in Germany, to mount Leica Viso lens heads with either, short focusing mounts, or on an M, Bellows II, on to my Nikon Bodies. I get Past-infinity focus-to-near macro with the focusing mount and to about 1.5:1 with the BellowsII. The above is useable with the 65, all 90's, all 135's, 200 & 280 Viso lenses. All in all, a pretty impressive lineup. Art Tafil ------ Unsubscribe or change to/from Digest Mode at: http://www3.telus.net/~telyt/lrflex.htm Archives are at: www.freelists.org/archives/leicareflex/
