M39x1 female thread to Leica M camera mount adapter

• Front side – M39x1 female thread
• Rear side – Leica M male bayonet mount

Machined from high quality aluminium alloy (body) and bronze (threaded insert).

This adapter allows using old Zenit lenses with M39x1 thread on cameras with Leica M mount.

The adapter is made 0.2mm shorter than a reference vlaue to allow some misadjusted lenses to reash infinity focus as well. You may need to add some shim(s) between the body and the instert to tune it for your particular lens. We don’t provide shims. You can simply cut them from printer paper (each sheet has 0.1mm thickness).

IMPORTANT: This adapter is purposed for old Zenit lenses (from Zenit-3M cameras). LTM lenses with fit mechanically, but they will focus to very short distances only (couple centimeters from the lens front).
