M42x1 female thread to Leica L (TL/SL) camera mount adapter for helicoids

• Front side - M42x1 female thread
• Rear side - Leica L-mount (formerly known as Leica T-mount, and available as TL and SL mounts now)

This adapter is purposed for M42 focusing helicoids or macro tubes only.

It does NOT provide infinity focus for lenses. DO NOT even try to use lenses with instant return diaphragm - you will damage your camera.
