Product Description

Upgrade your Sony 300mm f/2.8 GM lens with a foot built for speed and reliability. This Hejnar Photo replacement foot replaces the original factory mount to provide a native Arca-Swiss dovetail, eliminating the need for universal plates. The double-dovetail profile allows for clamping from both the top and bottom surfaces, making it ideal for rail-based setups and accessory mounting.

Integrated QD Carrying Security: For elite field use, this foot features a built-in QD socket. The QD system—trusted for decades by NASA and military agencies—features an anti-accidental-release design that is the safest way to carry heavy telephoto gear on a shoulder strap. The 4.55" length ensures a stable interface on tripod heads and gimbal mounts while keeping the overall profile lightweight.
