SmallRig Cage with Silicone Handgrip for Sony a6400 a6300 a6100

In this review the SmallRig Cage 3164 is evaluated as a compact, camera-specific rig for Sony a6400, a6300 and a6100 users who need extra protection and mounting options without a heavy shoulder rig. The strongest reason to buy is its combination of a removable, soft silicone handgrip and multiple mounting points, which deliver improved handheld stability and flexible accessory placement while keeping the camera compact for run-and-gun shooting.

Key Features

• Camera compatibility: Designed specifically for Sony a6400, a6300 and a6100, the cage fits the camera body to preserve access to controls and ports while adding protection.
• Silicone handgrip: The removable non-slip silicone handgrip improves handheld comfort and reduces fatigue during longer shoots.
• Mounting options: Two cold shoes, multiple 1/4'-20 threaded holes and ARRI 3/8'-16 locating holes let you attach monitors, microphones and articulating arms where needed.
• Secure locking: The cage secures via a 1/4'-20 base screw and an M2.5 side screw to prevent twisting and keep the camera stable.
• Arca-style quick tripod mount: An integrated Arca-type plate on the bottom allows fast transition to a compatible tripod head without removing the cage.
• Built-in convenience: A built-in screwdriver stores on the cage bottom for quick assembly and rubber pads help prevent camera scratching.

Who It's For

The SmallRig Cage 3164 is best for indie filmmakers, content creators and photographers using Sony a6400, a6300 or a6100 who want a low-profile protective cage that expands accessory options while improving handheld grip. Its compact footprint keeps the camera usable on gimbals or small tripods and makes it appealing for travel and run-and-gun setups.

Less suitable are users who need large shoulder rigs or integrated follow-focus systems; professionals who require heavy-duty modular systems with extensive rail support may prefer a more configurable cage. Also, if you need built-in power solutions, that is provided via separate SmallRig battery accessories rather than inside this cage.
