I am selling my Nikon Pro Lock Mount which has seen only a few lenses so far and was used only as spare.

This mount locks Nikon lenses as well as a PL mount.
Perfect for heavy lenses.
Attention: This mount was made for Version 1 Fan Motor.
If use Epic with Fan Motor 2, the Mount needs to be modified.
After checking with Optitec, there is no problem to convert the mount if needed.
Price : 750 USD.
The mount is currently in Tokyo.
