Product Description
The H122 replacement foot is designed to streamline your Canon EF 300mm f/2.8L IS II lens. By replacing the factory foot with this sleek, Arca-Swiss compatible solution, you get a dramatically stiffer mount with less vibration. The double-dovetail profile serves as an invaluable asset, giving you a reliable secondary clamping surface on the top side of the rail to attach heavy-duty flash brackets.
Installation Instructions:
To remove your original factory foot, use the M3 hex key tool that comes with the H122 to completely remove the four Canon mounting screws. To install the H122, use the four original Canon screws and secure the foot to the lens collar.
Check the tightness of your components periodically. For long-term security in rugged outdoor conditions, consider applying a drop of Loctite 242 removable threadlocker to the screws.
Precision-machined in the USA from solid aircraft-grade aluminum, the H122 reduces your vertical profile height, making your flagship telephoto glass easier to balance and fit into travel bags. Despite its lower height, the design leaves enough room for your fingers under the lens to freely use the lens focusing ring and allows the lens hood to be reversed for storage.
