## Long description

The K&F lens mount adapter for Fujifilm X / X-mount to M42 (KF06.058) is a metal construction adapter that allows mounting M42 screw-mount lenses on Fujifilm X-mount mirrorless cameras. This adapter provides a purely mechanical connection without electronic contacts, preserving manual aperture control and manual focus operation. It is designed to maintain correct flange focal distance for accurate focusing across the focus range when using vintage and third-party M42 lenses on Fujifilm X-series bodies.
Advantages
The metal construction ensures mechanical durability and stable lens seating, reducing play between lens and camera body. The adapter's precise machined mount maintains correct optical alignment for consistent image quality. Without electronic coupling, the adapter offers full manual control of aperture and focus, ideal for photographers who prefer mechanical lenses or wish to adapt legacy glass. It is compact and lightweight, keeping the camera system manageable for handheld and rigged use.
Suitable for
Adapting vintage M42 prime lenses to Fujifilm X-mount mirrorless cameras
Using manual-focus third-party M42 zooms with Fujifilm X-series bodies
Photography projects requiring manual aperture control and vintage lens rendering
Videography with adapted M42 optics for distinct character and manual focus pulling
Key specifications
Mount type: Fujifilm X / X-mount to M42 screw mount
Material: metal construction for mount and body
Connection: mechanical coupling only (no electronic contacts)
Compatibility: fits M42 screw-mount lenses and Fujifilm X-mount mirrorless cameras
Finish: precision-machined surfaces for stable lens seating
Weight and dimensions: compact and lightweight design for minimal added bulk
How to use
Attach the adapter to your Fujifilm X-mount camera by aligning the adapter mount with the camera mount and rotating until it locks in place. Screw the M42 lens into the adapter's M42 threaded opening until secure. Operate aperture and focus directly on the lens; the camera will typically require manual exposure settings and may use focus peaking or magnification aids for critical focusing. Remove the adapter by reversing the installation steps—unscrew the lens from the adapter first if desired, then unlock and rotate the adapter from the camera body.
Usage recommendations
Use manual exposure modes or aperture-priority with manual aperture lenses, and enable focus assist features on the camera to improve focusing accuracy. When mounting heavy vintage lenses, support the lens or use a tripod to minimize strain on the camera mount. Clean the contact surfaces before installation to avoid dust transfer to the sensor or lens elements.
