Lens mount adapter KiwiFotos for Leica M to Fujifilm X (KF4295)

The KiwiFotos lens mount adapter for Leica M to Fujifilm X (model KF4295) enables the use of Leica M-mount rangefinder lenses on Fujifilm X-mount mirrorless cameras. Designed to maintain a secure mechanical connection between vintage or modern M-mount optics and APS-C Fujifilm bodies, the adapter provides manual control over focus and aperture and positions the lens at the correct flange distance for accurate focusing across the frame.

Advantages

This adapter preserves the mechanical fit between Leica M lenses and Fujifilm X cameras without electronic coupling, providing a simple, robust solution for mounting M-mount optics. It allows full manual aperture and focus control as originally intended by rangefinder lenses and is compact and lightweight, adding minimal bulk to the camera setup. The adapter is constructed to align lenses accurately for consistent image plane positioning on APS-C sensors, supporting reliable manual focusing and framing.

Suitable for

• Photographers who want to use Leica M lenses on Fujifilm X-series mirrorless bodies
• Users of vintage rangefinder lenses seeking manual control on modern APS-C cameras
• Enthusiasts experimenting with adapted optics for portrait, street, and documentary photography

Key specifications

• Mount compatibility: Leica M-mount lens to Fujifilm X-mount camera
• Material: metal alloy construction for rigidity and alignment
• Finish: matte or anodised surface to minimise reflections
• Support: manual aperture and manual focus only, no electronic contacts
• Size and weight: compact, lightweight design suitable for hand-held use

How to use

Attach the Leica M lens to the adapter by aligning the lens bayonet with the adapter mount and turning until it locks. Then align the adapter with the Fujifilm X camera mount and rotate until it engages securely. Set the camera to manual or aperture-priority mode and use the lens’s manual aperture ring to adjust exposure. Focus manually using the camera’s focus assist features (focus peaking or magnification) if available. Because the adapter does not transmit electronic data, set exposure parameters and focus confirmation using the camera’s controls and displays.

Usage recommendations

For best results, use focus peaking or magnified live view when focusing, and meter with the camera in manual or aperture-priority mode. When mounting older lenses, check for secure mechanical engagement and avoid excessive force when locking or unlocking. Store the adapter and lenses in a dry, dust-free environment to maintain mount surfaces and ensure reliable coupling over time.
