Ok, I got my copy and have some problems when mounting the lens:
1) The aperture lever hits the bottom of the mirror chamber. When I stop it down before mounting the lens, the aperture opens up again because the lever is pushed back.
2) The mirror hangs at any FL. I removed the little \"block\" screwed onto the metal shroud within which the rear element moves.
3) It doesn\'t quite seem reach infinity focus. (Doing further verification.)
Any ideas on how to solve the problem with the aperture lever? Interestingly, on my previous copy that focused way beyond infinity the aperture lever sat quite a bit deeper and didn\'t stick out past the metal shroud, and it didn\'t have any mirror issues on my 5Dmk1. I wonder if mine does the opposite thing now (perhaps it shouldn\'t stick out? It\'s only a fraction of a millimeter).
