Urth Lens Mount Adapter M42 Lens to Leica L Camera

No, this is a manual adapter. Autofocus and other electronic camera functions are not supported. You will need to manually focus and set exposure.

While designed for standard M42 lenses, very long protruding rear elements might interfere with the camera's internal mechanisms. Always check compatibility for specific lenses.

Infinity focus capability can vary depending on the specific lens and adapter tolerances. Manual adjustment is required, and achieving perfect infinity focus may not be possible with all lens/adapter combinations.

Most M42 lenses have an aperture ring directly on the lens. Some may have an 'A/M' switch; ensure it is set to 'M' for manual control when using this adapter.

This adapter is backed by Urth's lifetime warranty.

The adapter is designed for L-mount still cameras. Compatibility with cinema cameras may vary and should be confirmed with the cinema camera manufacturer.

Ensure no debris is present on the camera mount or adapter. Realign the mounting marks carefully and try again. Check if the lens protruding too far back might be interfering.

This is a common characteristic of many lens mount adapters and may be due to manufacturing tolerances or the specific lens design. Manual focus adjustment will be necessary, and infinity focus may not be achievable with all combinations.

Confirm that the lens aperture is being manually adjusted on the lens itself, and that the camera is set to manual exposure mode. Ensure the lens is set to its 'A' (auto-aperture) position if it has one and the adapter supports it for manual control.

Press and hold the release button (if applicable on your camera model) while rotating the adapter or lens counter-clockwise. Ensure you are not forcing the mechanism.
