The lightweight Professional Camera Cage Kit from SmallRig provides accessory mounting and protection for your a7S III mirrorless camera, and it includes an HDMI cable clamp and a wooden side handgrip.
The camera mounts onto this formfitting aluminum cage with an integrated 1/4"-20 screw, and it features multiple 1/4"-20 and 3/8"-16 accessory threads, ARRI-style accessory threads, a NATO rail, a shoe mount, strap slots, and front threads for a separately available lens adapter.
The contoured wooden handgrip mounts onto the cage using two 1/4"-20 thumbscrews, and it features accessory threads and a shoe mount for additional accessories. The HDMI cable clamp mounts onto the cage using a 1/4"-20 screw and prevents your HDMI cable from pulls.
