Product Description

This Hejnar Photo replacement foot is engineered specifically for the Fujifilm XF 50‑140mm f/2.8 R LM OIS WR lens. It provides a stronger, more stable mounting platform than the factory foot while adding the versatility of an integrated Quick Detach (QD) socket. The QD interface accepts standard push‑button QD mounts, offering a secure and reliable connection for QD‑compatible straps and support systems.

The QD system has been trusted for decades by NASA, law enforcement, and military agencies due to its resistance to accidental release and its ability to maintain a locked connection under dynamic movement. The integrated QD socket allows the lens to be carried safely and confidently while maintaining full compatibility with Arca‑type clamps, rails, and tripod heads.

The foot features a precision‑cut double‑dovetail profile, allowing clamping from either the top or bottom surface. This design is ideal for rail‑based setups, macro stages, gimbal heads, and multi‑axis support systems. Two M3 safety‑stop screws are installed at the ends of the dovetail to help prevent accidental slide‑out when a clamp is not fully closed.

The mounting platform includes both 1/4‑20 tapped hole for direct attachment of accessories, monopods, or tripod heads. The 3.725 inch length provides a stable mounting surface while maintaining a compact footprint suitable for field use. The foot weighs only 4 oz (113 g), offering strength without unnecessary bulk.

Each foot is CNC‑machined from 6061‑T6 aluminum for strength, precision, and dimensional stability. The black hard‑coat anodized finish provides excellent wear resistance, while stainless‑steel hardware ensures corrosion resistance and long‑term reliability. Like all Hejnar Photo components, this foot is manufactured in the USA with tight tolerances and professional‑grade machining standards.
