SmallRig Cage for Sony FX30 and FX3 Reviews

Slim For SmallRig

By Stephen
Rated 5 out of 5
Date: 2025-12-04

This Cage Has A Slimmer Design Compared With Previous SmallRig Cages I Have Owned, Especially Where It Counts On The Right Hand-grip. The Locations Of The 1/4-20 Mounting Have Worked Well For My Rig Preferences. And The Three Mounting Points Made It Very Secure. This Has Been My Favorite SmallRig Cage Purchase So Far.

Love it, fun to rig
