## Summary description

Mechanical lens adapter K&F KF06.277 enables mounting M39 (M-39) lenses with 50–75 mm focal length onto Leica M-mount cameras. It provides physical coupling for compatibility between lens and camera bodies without electronic contacts, preserving manual aperture and focusing control. Useful for photographers using vintage or third-party M39 lenses on Leica M-rangefinder bodies for portrait and street photography.

## Long description

Mechanical lens adapter K&F KF06.277 allows mounting M39 (M-39) lenses with a focal length of 50–75 mm onto Leica M-mount rangefinder cameras. The adapter provides a secure mechanical connection between the lens and the camera body, preserving manual aperture control and manual focusing. It does not transmit electronic signals, so lens metering and electronic functions depend on camera compatibility and lens characteristics.
Advantages
The adapter is designed for a precise fit to maintain correct flange focal distance and reliable mechanical coupling. Its metal construction ensures durability and stable alignment during use. By enabling the use of M39 lenses on Leica M bodies, the adapter expands lens options for portrait and street photography, allowing photographers to utilise vintage optics and unique rendering. The lack of electronic contacts simplifies the mechanical interface and reduces potential points of failure.
Suitable for
Photographers who want to use 50–75 mm M39 lenses on Leica M-mount rangefinder cameras
Portrait and street photographers seeking vintage lens character and manual control
Users adapting third-party or legacy M39 lenses to modern Leica M bodies for creative effects
Key specifications
Mount compatibility: M39 (lens) to Leica M (camera)
Supported lens focal length: 50–75 mm
Connection type: mechanical coupling without electronic contacts
Material: metal body for durability and alignment stability
Designed flange focal distance: maintains correct registration for rangefinder focus
How to use
Align the red or marked index on the adapter with the corresponding mark on the M39 lens, then thread or seat the lens onto the adapter until secure. Next, align the adapter’s Leica M mount index with the camera’s mount mark and rotate to lock the adapter with the lens onto the camera body. Set the camera to manual or rangefinder focus mode as required. Because the adapter has no electronic contacts, aperture and focus must be controlled directly on the lens; exposure metering should be verified on the camera or via test shots.
Usage recommendations
Handle the adapter and lenses carefully to avoid cross-threading; ensure clean contacts and mounts before attaching. Use manual focusing aids available in Leica M cameras (rangefinder, focus magnification where applicable) and check focus and exposure with test frames. When using vintage glass, bracket exposures and consider shooting in RAW to retain maximum image detail.
