Product Description

The H113 replacement foot is the ideal professional upgrade for photographers looking to maximize the stability of their Canon EF 300mm f/2.8L USM non-IS 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.

Despite its strong clearance, please note that the geometry of this foot does not allow the lens hood to be reversed for storage. It still leaves plenty of room for your fingers under the lens to freely use the lens focusing ring during active shooting.

How to Install the H113:
To remove your original factory foot, use the standard M3 hex key tool included with the H113 to completely extract the four Canon mounting screws. To install the H113, simply use those 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.
