Product Description

Enhance the performance of your Sigma Sports lens with a replacement foot built for the field. The SIGFR-001 provides a native Arca-Swiss foundation, eliminating the need for universal adapter plates and reducing potential flex. Its double-dovetail design ensures universal compatibility with Arca-style clamps from RRS, Kirk, Acratech, and Wimberley, allowing you to mount the foot into a head while simultaneously attaching flash brackets or rails to the upper dovetail.

The foot is carefully engineered to maintain the full functionality of the lens. The height provides comfortable clearance to access the focusing ring while shooting handheld, and the compact profile ensures the lens hood can still be reversed for storage.

Simple Installation

1. Use the included M3 hex key to completely remove the four factory Sigma mounting screws.
2. Position the SIGFR-001 foot and secure it to the lens collar using the provided M4 mounting screws.
3. Pro Tip: If your mounting screws tend to loosen over time, consider using a drop of Loctite 242 (blue) for added security.
