Product Description

This Hejnar Photo replacement foot is engineered specifically for the Canon RF 600mm f/11 IS STM lens. It provides a stronger, more stable mounting platform than the factory foot while adding the versatility of an integrated stainless steel Quick Detach (QD) socket. The QD interface accepts standard push‑button mounts, offering a secure and reliable connection for compatible straps and support systems.

The QD system has been trusted for decades by NASA, law enforcement, and military agencies for its secure, anti‑accidental‑release design, especially when the camera is carried on a strap. This allows a lens to be carried safely and confidently in the field 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‑accessory setups. The dual‑surface dovetail also perfectly accommodates flash brackets and accessories that require a secondary clamping surface.

Each foot is CNC‑machined in the USA from solid aircraft-grade 6061‑T6 aluminum for extreme strength and dimensional stability. If mounting screws happen to loosen over time due to rugged field use, a small amount of removable thread locker such as Loctite 242 may be applied for added security.
