Arca-Swiss Replacement Foot for Metabones Adapters | Extended Clearance

The Hejnar Photo Replacement Foot is a dedicated structural upgrade custom-designed for Metabones (Gen 2, Gen 3, and Gen 4) smart adapters, including the popular Nikon F-mount to Fujifilm X-mount adapter. Engineered with an integrated Arca-Swiss compatible dovetail profile, this heavy-duty foot serves as a direct swap for the factory mount. It increases physical height to provide essential vertical clearance when deploying wide-barrel lenses or bulky support setups on professional tripods and monopods.

Compatibility Note: This replacement foot is built exclusively for Metabones lens adapters that feature a standard fixed base WITHOUT an integrated aperture control ring. It is not compatible with adapters featuring a built-in mechanical adjustment collar, such as the Nikon G to Fujifilm X-mount or the Nikon F to Sony E-mount rotating ring models.

Quick Overview & Key Features

• Dedicated Adapter Compatibility: Direct physical upgrade tailored to fit the mounting channels of Metabones Gen 2, Gen 3, and Gen 4 optical/smart adapters.
• Enhanced Height Clearance: Elevated profile bypasses the space limitations of the stock adapter foot, allowing wide-diameter lenses to clear monopod heads and tripod clamp knobs cleanly.
• Integrated Arca Dovetail: Features a native Arca-Swiss profile machined along the bottom track to eliminate the flex, vibration, and extra weight of third-party quick-release plates.
• Universal Support Fit: Dovetail profile ensures a perfect, zero-play lock inside standard quick-release clamp systems from RRS, Kirk, Wimberley, Leofoto, and Markins.
• Streamlined Flat Profile: Flat, high-traction mounting surface guarantees absolute metal-on-metal alignment against the adapter body, stopping twisting under heavy leverage.
• Fail-Safe Security Stops: Equipped with dual pre-installed bottom safety screws to prevent your valuable lens and camera setup from accidentally sliding out of a loosened clamp.
• Premium US Craftsmanship: Precision CNC-machined from a solid block of aircraft-grade 6061-T6 aluminum.
• Rugged Hard-Coat Finish: Treated with a professional black hard-coat anodized layer for advanced resistance against outdoor elements, scuffs, and field transport wear.

Product Description

The Hejnar Photo Arca-Swiss Replacement Foot for Metabones solves a frustrating design limitation commonly encountered by wildlife, sports, landscape, and action photographers using adapted glass. The original foot supplied with factory Metabones adapters sits exceptionally low to the lens axis. Consequently, when trying to lock your camera system onto wide tripod platforms, large monopod heads, or heavy quick-release clamps, the barrel of your favorite fast-aperture lenses will physically bottom out against the support hardware. This prevents a clean lock, limits tracking range, and places unnecessary strain on your lens mount.

This custom-engineered replacement foot completely resolves that physical bottleneck. By increasing the vertical offset distance between the adapter collar and the bottom plate track, it provides the critical spatial clearance required to run wide-barrel primes or large pro zooms without obstruction. The bottom of the foot is machined with a single, low-profile Arca-Swiss dovetail profile, making it a permanent part of your lens train. This unibody design avoids the stack tolerance error, twisting, and subtle micro-vibrations associated with stacking separate screw-on adapters together.

Bespoke-crafted in the USA from solid aircraft-grade aluminum, this accessory offers exceptional load-bearing rigidity to keep your camera body well-balanced and firmly supported. The package comes ready to mount with matching high-tensile connection screws that lock square into the Metabones adapter socket. Finished with a rugged black hard coat built to withstand severe field use, this replacement foot delivers the unyielding stability, fluid balance control, and liflelong durability your optical system requires.
