Sorry, long. I got carried away enthusiastically writing about my latest adapter "adventure".
I was aware that during the FD mount era Canon sold a number of adapters ("converters") from something else to FD mount. I suppose Canon could do that because the flange distance for FD mount is a bit shorter than several other mounts.
Recently I picked up a Canon lens mount converter "E" (Exakta to FD) and subsequently a "P" (M42 to FD) and I must say I am really impressed with the quality of these. I use these together with my Novoflex FD to M43 adapter; yes these are somewhat expensive but I am really happy with the quality of these Novoflex adapters. They are as good as the real thing in my opinion.
Anyway, both the Canon lens mount converter E and P on my Novoflex FD to M43 adapter have infinity focus right where I like it to be, namely fractionally short of the hard stop. Same goes for the Novoflex FD to m43 using an FD lens by the way.
I must add that I find a consistent difference in M42 lenses between Schneider Kreuznach on the one hand and everything else I have tested on the other hand, with the Schneider lenses being a bit too long so they don't quite focus to infinity. Not on my Novoflex M42 to M43 adapter (which could be an adapter problem), but also not with Canon converter P (the FD to M43 adapter the converter P is attached to focuses perfectly with FD lenses, so no problem there). Carl Zeiss Jena and Meyer lenses are perfect. Perhaps an East Germany - West Germany thing? I bought a Chinese adapter specifically for the Schneiders with the understanding that the Chinese adapter would be significantly short.
Since Novoflex don't and won't make an Exakta adapter (I asked), finding a really good Exakta adapter has been a bit of a quest. I settled on K&F but these are quite a bit too short. I guess that is to ensure infinity focus but the result is that infinity focus ends up being about 2/3 of the way to the hard stop. I had to add add a shim to the K&F adapter to get it closer. This Canon E adapter with my Novoflex FD to M43 adapter: perfection. The only thing about this E adapter is that removing it from the FD mount is a bit tricky (watch out for broken fingernails). The P adapter uses the standard FD rotating collar design.
The P adapters for M42 are quite common, the E's are somewhat uncommon in Europe (where I live) so i was lucky to be able to pick one up.
Bottom line: if you find yourself needing to adapt either M42 or Exakta to Canon FD, then I recommend you look at these.
Canon also made an A (M39 lens to FD body, macro only), B (FD lens on M39 body) and an N (Nikon lens on FD body). The A and B are quite common. The N is rare, and apparently also is called either "MC-N" or "BH MT. CONVERTER N". If Canon made any besides these five then I am not aware of it.
