8x11 Posted May 10, 2020 Share Posted May 10, 2020 Rare is an overused word, but I cannot find many references to this: an adapter for Canon screw lens to canon FL lenses, from 1966. New in the box. Has anyone else seen one of these: the P adapter was common but not the A or B adapter. 2 Link to comment Share on other sites More sharing options...
jim_bielecki1 Posted May 10, 2020 Share Posted May 10, 2020 I have one. It allows you to use a Leica screwmount lens on a Canon R/FL/FD SLR. Mainly used for close-up and macro work. Works well. 2 Link to comment Share on other sites More sharing options...
SCL Posted May 10, 2020 Share Posted May 10, 2020 I've been using a Canon B mount converter for several years allowing the use of Canon SLR lenses in a stopped down mode on my Leica rangefinder bodies (LTM or M with another LTM->M ring), as well as my 17mm Tamron Adaptall lens in a Canon FD adapter. Have to use zone focusing, but my negatives have been sharp and well exposed. 2 Link to comment Share on other sites More sharing options...
jim_bielecki1 Posted May 10, 2020 Share Posted May 10, 2020 Yep, the lens mount converter B is a way to use R/FL/FD lenses on any M-series Leica. I frequently use my Canon FD lenses on my M240 using "Live View" which allows me to see the image on the screen. You use "focus peaking" to focus. A great way to keep using my old Canon breechlock lenses. 2 Link to comment Share on other sites More sharing options...
8x11 Posted May 10, 2020 Author Share Posted May 10, 2020 Thanks for this. This accessory seems more useful than I thought. 1 Link to comment Share on other sites More sharing options...
cmuseum Posted May 11, 2020 Share Posted May 11, 2020 Converter A and B can be combined with M39 extension tubes for building R/FL/FD extension tubes: I'd agree that Converter A and B are not found as often as Converter P but they are not exactly rare. These are all more or less recent ebay finds: I think the least common ones are the Converter E (Exakta) and N (Nikon), with the N version clearly being found least often and selling for the highest prices: 2 Link to comment Share on other sites More sharing options...
jim_bielecki1 Posted May 11, 2020 Share Posted May 11, 2020 The Lens Mount Converter N is rare. 1 Link to comment Share on other sites More sharing options...
chuck909 Posted May 16, 2020 Share Posted May 16, 2020 (edited) I had both, too and used them with extension tubes. And with an extra converter to "C" mount. I was able to use my Canon FD lenses on my 16mm movie camera. Edited May 16, 2020 by chuck909 Link to comment Share on other sites More sharing options...
bob_hartemink Posted May 27, 2020 Share Posted May 27, 2020 Here is the Converter B in action with the wonderful FL 19mm on my Canon P LTM rangefinder. 3 Link to comment Share on other sites More sharing options...
awahlster Posted June 12, 2020 Share Posted June 12, 2020 I have both. Don't have a P though no P lenses. Link to comment Share on other sites More sharing options...
