Product Description

This replacement foot is designed specifically for the Canon RF 600mm f/4 L IS USM lens. It features a dual‑dovetail profile, allowing clamping from either the top or bottom surface—ideal for flash brackets, rails, and multi‑accessory setups.

To remove the factory Canon foot, use the included M3 hex key to remove the four original mounting screws. Install the replacement foot using the four supplied screws and secure it to the lens collar.

A Quick Detach (QD) socket is integrated into the foot, enabling the use of standard push‑button QD mounts. The QD system has been trusted for decades by NASA, law enforcement, and military agencies for its secure, anti‑accidental‑release design.

If mounting screws loosen over time, a removable threadlocker such as Loctite 242 may be applied for additional security.
