• Front side - M42x1 female thread
• Rear side - Pentax 645 camera mount
• Added optical path - 1mm

Machined from high quality aluminium alloy.

This adapter allows using lenses, macro tubes or bellows with M42x1 thread on cameras with Pentax 645 mount.

IMPORTANT: this adapter does not allow a lens to focus to infinity. Any M42x1 lens will focus to very close distances only (a few centimeters from the lens front).

But you can use it with a view camera, or with a tilf-shift Pentax 645 to Fuji GFX adapter.
