Like to experiment with legacy lenses on your modern Canon DSLR? I just sold my 1DS Mk III and lenses on ebay. I have three top quality Voigtlander adapters. I seem to remember paying around $150 or so each (the M42 was probably less). I have M42----> EOS adapter, a Contax/Yashica---->EOS adapter, and Leica R--->EOS adapter. First offer for $150 for all three of them gets them, post paid.
