Product Description

Enhance the performance of your Sigma 500mm f/4 Sports lens with a foot built for stability and versatility. The H118 provides a native Arca-Swiss foundation, eliminating the need for universal adapter plates. Its double-dovetail design is a standout feature, allowing you to secure the lens into a tripod head while simultaneously attaching flash brackets or rails to the secondary clamping surfaces.

Designed for photographers who demand a more compact and balanced setup, the low-profile height brings the lens closer to the center of rotation on gimbal heads. This results in smoother movements and easier handling of your heavy telephoto glass in the field.

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 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.
