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

Thanks for the info.. Based on responses I would say I am looking for the 
highest quality chipped adapters to mount the Leica R lenses onto the Canon 
EOS 5D Mark II full frame digital body.
