Product Description

This replacement foot is the ideal professional upgrade for photographers looking to maximize the stability of their Canon FDn 500mm f/4.5L lens. This plate seamlessly integrates an Arca-Swiss compatible dovetail, allowing you to slide the lens directly into gimbal heads, ball heads, and tripod clamps without adding the bulk of extra plates.

The double-dovetail profile provides exceptional versatility. You can mount your primary camera setup to your tripod using the bottom track while using the top track to clamp on external flash brackets, video accessories, or macro rails.

A standout feature of this model is the integrated stainless steel Quick Detach (QD) socket. This military-grade carry system allows you to click on standard push-button sling-style straps for rapid transitions and comfortable outdoor carry, then detach instantly to mount onto your rig. The QD system has been trusted for decades by NASA, law enforcement, and military agencies for its secure, anti-accidental-release design.

How to Install:
To remove your original factory foot, use the included M3 hex key tool to extract the four Canon mounting screws. Install the replacement foot using the four supplied screws to secure the new replacement foot tightly to the lens collar. For added security in rugged outdoor conditions, consider applying a drop of Loctite 242 removable threadlocker to the screws.
