## Summary description

Lens mount adapter by KiwiFotos (model KF3975) enables use of Leica M-mount lenses on Canon RF-mount cameras. The mechanical adapter provides physical compatibility between lens and body while retaining manual focus and aperture control from the lens. Suitable for photographers who want to adapt rangefinder glass to mirrorless RF bodies for creative or specialist use.

## Long description

The Lens Mount Adapter KiwiFotos for Leica M to Canon RF - KF3975 allows photographers to mount Leica M-mount lenses on Canon RF-mount mirrorless cameras. This mechanical adapter creates a precise physical connection between rangefinder lenses and RF bodies while preserving the manual focus and aperture control inherent to the original lenses. It is intended for creative, technical, and specialist use where adapting legacy or vintage glass to modern mirrorless systems is required.
Advantages
The adapter is entirely mechanical, ensuring there is no electronic communication between lens and camera, which preserves the original optical characteristics and manual operation of Leica M lenses. Its construction provides accurate flange distance conversion and a secure bayonet fit to minimize play and maintain alignment. The compact, lightweight design adds minimal bulk to the lens-camera combination, and the adapter is compatible with a wide range of M-mount optics, including vintage and modern manual lenses.
Suitable for
 Photographers adapting Leica M lenses for use on Canon RF mirrorless bodies
 Portrait, street, and documentary photographers using manual-focus rangefinder glass
 Creative photography projects that require characteristic rendering of vintage lenses
 Technical and product shooters who need specific focal characteristics from M-mount optics
Key specifications
 Mount conversion: Leica M to Canon RF
 Type: Mechanical adapter without electronic contacts
 Material: metal construction for durability and stable mounting
 Finish: matte surface to reduce reflections
 Compatibility: supports manual focus and manual aperture control from lens
 Weight and size: compact and lightweight to preserve handling balance
How to use
Attach the adapter to the Canon RF camera body by aligning the adapter bayonet with the camera mount and turning until it locks into place. Mount the Leica M lens onto the adapter in the same manner as you would mount it on an M-mount camera, ensuring a secure fit. Focus and set aperture directly on the lens; camera will not detect electronic aperture or focus data. Use camera in manual or aperture-priority modes with appropriate focus aids such as focus peaking or magnification to achieve accurate manual focus.
Usage recommendations
When using adapted lenses, enable viewfinder aids (focus peaking, magnified live view) for precise focusing. Check for possible vignetting or optical characteristics that vary from native RF lenses and adjust framing and exposure accordingly. Remove the adapter when not in use to protect lens and camera mounts from dust and damage.
