Product Description

The H118 replacement foot is designed to streamline your Canon 400mm f/2.8L setup by replacing the bulky factory foot with a sleek, low-profile Arca-Swiss compatible solution. The double-dovetail design is a standout feature, providing a secondary clamping surface on the top of the rail for secure attachment of flash brackets or other lens-mounted accessories.

Installation Instructions:
To remove the original Canon foot, use the included M3 hex key tool to remove the four mounting screws.

• IS Version II: Use the four screws provided with the H118 to secure the new foot to the lens collar.
• IS Version I: Use the four original screws from the existing Canon foot for mounting.

For long-term security, it is recommended to check screws periodically; for permanent installation, consider using a small amount of Loctite 242.

Precision-machined in the USA from aircraft-grade aluminum, the H118 reduces the height of your lens setup, making it more stable on a tripod and easier to fit into gear bags.

Simple Installation

1. Use the included M3 hex key to completely remove the four factory mounting screws from the original foot.
2. Position the H118-C foot and secure it to the lens collar using the four provided mounting screws.
3. Note: If your mounting screws tend to loosen over time, we recommend using a drop of Loctite 242 (blue) for long-term security.
