P6 Adapter for a Mamiya 645

  1. I know this is a long shot, but here goes...

    So I bought this adapter a while back that allows me to use P6 mount lenses on my Mamiya 645. The adapter is now stuck to the lens and it seems there is no possible way to get it off. I've tried EVERYTHING. It has the slightest bit of give to it, but that's it. Has anyone else experienced this? If so, what did you do?

    Thanks in advance - Steve
     
  2. Is it a former Soviet-built lens or adapter by any chance?

    The P6-style mount can easily bind if the lens bayonet isn't well-made or out of tolerance.

    Try gently tapping the knurled-ring of the adapter with a rubber hammer or maybe a length of wood. Work around the knurled ring in a clockwise direction, as seen from the rear of the lens - the 'undo' direction in other words.

    You'll still need to grab the ring and undo it by hand, but the tapping should ease it enough to undo.... eventually.

  3. I find a strap wrench works well on the ring, you can't really hurt the lens or adapter with it.
