M65x1 female thread to Pentax 67 camera mount adapter, 3mm flange

• Front side - M65x1 female thread
• Rear side - Pentax 67 mount
• Flange thickness - 3mm

This adapter allows using Chinese focusing helicoids with M65x1 thread mount on Pentax 67 cameras.

Bit difficult to install/remove due to 3 mm thickness, but this is necessary to allow infinity focus for some lenses. You can use installed M65 helicoid to mount/remove this adapter more easily.
