Product Description

The H127-QD replacement foot is the ideal professional upgrade for photographers looking to maximize the stability of their Canon EF 500mm f/4.0L IS II USM lens [127-QD]. 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 (like Black Rapid or Magpul) for rapid transitions and comfortable outdoor carry, then detach instantly to mount onto your rig.

How to Install the H127-QD:
To remove your original factory foot, use a standard M3 hex key tool (included with the H127 series) to completely extract the four Canon mounting screws. To install the H127-QD, simply use the four original Canon 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.
