Product Description

Upgrade your Sigma 150-600mm Sport lens with a foot built for rugged reliability and modularity. The SIGFR-005 eliminates the need for universal adapter plates by providing a rock-solid, built-in Arca-Swiss dovetail. The precision engineering ensures a zero-flex connection to your tripod or monopod head, essential for sharp telephoto results.

Integrated Carrying Security: This foot incorporates two stainless-steel QD (Quick Detach) sockets, providing the safest carrying method available. The QD system—trusted for years by NASA, law enforcement, and military agencies—uses a secure push-button mechanism that inhibits accidental removal. This is the ideal solution for photographers who carry heavy gear on professional shoulder slings, ensuring your equipment stays secure even in active field environments.

Simple Installation

1. Completely remove the original factory foot from the lens collar.
2. Install the SIGFR-005 using the provided mounting screws.
3. Pro Tip: If your mounting screws tend to loosen over time, we recommend applying a drop of Loctite 242 (blue) for added security.
