Brass Unbranded L39 to M42 Lens Mount Adapter

The Brass Unbranded L39 to M42 Lens Mount Adapter is a handy tool for photographers and tinkerers who love mixing systems. It allows you to mount Leica Thread Mount (L39/LTM) lenses onto M42 screw-mount cameras, bellows, or focusing helicoids, making it a useful piece for macro setups, enlarging lens experiments, or custom builds.

This adapter is made of solid brass, giving it durability and a snug, secure fit. While it doesn’t carry a brand name, it’s well-machined and holds alignment well under typical use. Perfect for DIY shooters, vintage lens lovers, and anyone pushing the boundaries of format or flange distance.

Condition: Good

This adapter is in good condition, showing some light cosmetic wear consistent with use. Threads are clean and smooth, and the adapter mounts securely on both L39 and M42 ends with no slop or wobble.
