Product details

The K&F Concept M42 to Fujifilm X lens adapter allows photographers to connect classic M42 screw mount lenses to mirrorless Fujifilm X-series cameras. This precision-crafted adapter maintains full manual control over aperture, focus, and other lens functions while ensuring a secure connection between the lens and camera body. Made from durable aluminum alloy with brass bayonet mounts, the adapter features a compact design of approximately 15 mm in length and weighs 45 g, minimizing its impact on the overall system balance. The matte black finish reduces internal reflections and light scattering, while the precise machining ensures the correct flange distance for accurate focus adjustment. This adapter supports infinity focus with compatible lenses, offering photographers creative possibilities with classic M42 optics on modern Fujifilm X-bayonet systems. The easy installation requires no tools or modifications to the lens or camera, making it accessible for photographers of all experience levels. Compatible with all Fujifilm X-series cameras, this adapter expands experimentation opportunities with various focal lengths and optical characteristics from the extensive M42 lens ecosystem. The product includes a microfiber storage pouch for transport and storage. It is important to note that no electronic communication between the lens and camera is supported, requiring manual exposure settings and focus confirmation through the camera viewfinder or LCD screen. This adapter provides a practical solution for photographers looking to expand their creative toolkit by integrating historical lenses into modern digital imaging systems.
