SmallRig 3639 Overview

Protect and customize your Sony Alpha a1, a7 IV, a7R IV, or a7S III rig for any run-and-gun shoot with the Half Camera Cage from SmallRig. Multiple 1/4"-20 and ARRI 3/8"-16 threads plus a NATO rail allow for the mounting of secondary monitors, articulating arms, or other accessories to increase the recording quality of your camera. A cold shoe mount at the top of the half cage offers an additional mounting point for accessories like a shotgun microphone or wireless receiver.

The cage is constructed with aluminum alloy, steel, and silicone for a durable, anti-slip design that doesn't impede access to your camera's controls, battery, and stock handgrip. An Arca-type baseplate with a 1/4"-20 screw and locking side plate secure the camera in place and allow for easy transitions from handheld to a tripod or compatible gimbal stabilizer.

    will this half-cage fit the Sony Alpha 9ii?
    Asked by: Chris
    We cannot guarantee this cage would fit the a9 II, as it was designed to fit exclusively on the Sony Alpha 7 IV, 7S III, 7R IV, and A1. The only SmallRig cage currently available that’s designed to fit the a9 II is the SmallRig Light Camera Cage for Sony a7R IV & a9 II (BH #SM2917 MFR #2917) - https://www.bhphotovideo.com/c/product/1603712-REG/smallrig_2917_light_cage_for_sony.html
