We tested Matthias Uhlig’s MBF Filmtechnik PL lens to Canon EOS adapter on a Canon EOS 7D and 1D Mark IV. The adapter works with more lenses than we thought–not just the Angenieux 24-290. Angenieux Optimo 15-40mm and 28-70mm zooms are perfect with this mount. No interference with the mirror, so you can pre-focus optically before switching to live view. The mount also works with Clairmont Swing-Shift lenses. Be sure to use lens supports and rods.
