I have been shooting with a NEX-7 and Minolta Rokkor 24/2.8, 50/1.4, 85/1.7 and M-Rokkor 40/2 and 90/4 lenses for the last year.
I recently bought a Canon 6D. I sent Jim Buchanan the Rokkor 24/2.8, 50/1.4, 85/1.7 to convert to EOS. Since the MD/MC mount is obsolete, it made no sense not to buy the Canon EF adapter for the NEX-7 and convert the Rokkors to EOS so that all my lenses fit both cameras (with exception of M-Rokkors).
Jim is a true pro and had no problems converting all lenses. I have mirror clearance and dead-on infinity focus with each lens Jim converted.
