Product Description:
Replacement foot for: Sigma 500mm f/4 DG OS HSM Sports Lens

Double-dovetail design allows for dual clamping surfaces on rail

To remove original foot, use the M3 hex key tool that comes with the FIGFR-001 to completely remove the four Sigma mounting screws.

To install the SIGFR-001, use the four original Sigma screws and secure the foot to the lens collar.

If your mounting screws loosen over time, consider using Loctite 242 for security.

Foot leaves enough room for your fingers under the lens to freely use the lens focusing ring, and allow hood reversal for storage.
