Product Description

The H118 replacement foot is designed to bring superior stability and smooth handling to your massive Canon EF 800mm f/5.6L IS lens. By replacing the bulky factory foot with this sleek, low-profile Arca-Swiss compatible solution, you decrease the overall lens height and maximize torsional rigidity. 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 included with the H118 to completely extract the four Canon mounting screws. To install the H118, use the four provided mounting screws to firmly secure the new replacement 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 H118 reduces your vertical profile height, making your flagship super-telephoto glass much easier to balance and fit into travel cases.
