Product Overview

The SmallRig 3667C Cage is a precision-engineered aluminum alloy frame designed specifically for the Sony Alpha 7-series full-frame mirrorless cameras.

It provides robust protection and extensive mounting interfaces for professional rigging. The cage secures to the camera via a 1/4"-20 bottom screw and a side locating block, ensuring zero deflection during operation.
