Subject: [Leica] Adapters: Leica R lens to Canon EOS (5D Mark II or 1Ds Mark III)

Hi again Wayne,

I have chipped adapters for Leica-R - EOS, Contax/Yashica to EOS, M42 to 
EOS and Olympus OM to EOS from - all fit and 
function very well.

Any initial looseness is easily corrected by slightly widening the slits 
in the bayonet lugs of the adapter with a flat-bladed jeweller's 
screwdriver (I have read that this is also the cure for loose 
Cameraquest adapters - IIRR the trick came from David Young over on the 
LRFLEX list.).

I have however noticed tolerance problems with their CY adapters (some 
lock correctly, some don't), though I'm not quite sure whether the lens 
mount was at fault - one Zeiss lens refuses to lock even with a 
high-quality (and expensive) adapter from Huppert in Germany (rumour has 
it that it's actually made by Zeiss, Novoflex or Leica - for what that's 
worth :-) ).

(I also have their CY to Leica-M, Leica-R to Leica-M, PK to EOS, 
Adaptall-2 to EOS and a Canon to Canon with a correction lens that works 
ok too.)

They also do a simple ring adapter that converts M39 to M42 - really 
useful when attaching M-lenses to a bellows with an SLR lens mount

The only really poorly constructed adapters I've had from them were for 
Rollei QBM to EOS.

I think I must be an adapter addict - I also use a Topcon/Exakta - EOS 
adapter and an excellent QBM to EOS (now discontinued) from Kindai

I've had no problems whatsoever with the company - they are even based 
here in Hannover where I am, so I can go round and beat on their door if 
anything goes wrong :-)
