SMALLRIG BMPCC Cage for Pocket Cinema Camera 4K & 6K - Custom

In this review the SMALLRIG BMPCC cage is examined for filmmakers who use the Blackmagic Design Pocket Cinema Camera 4K and 6K and need a lightweight, highly configurable protective frame. The bottom line: this cage delivers strong protection and lots of mounting options without blocking battery or SD access, making it a solid pick for owners who plan to rig microphones, handles or gimbals. It is not compatible with the 6K Pro, so double-check your model before buying.

Key Features

• Camera fit: Specifically shaped for the Pocket Cinema Camera 4K and 6K so buttons, battery and SD card remain accessible during use.
• Secure mounting: Two screws and two detachable anti-twist pins lock the camera in place to reduce movement on set or when using a gimbal.
• Protective design: Rubber pads on the bottom protect the camera finish from scratches while adding a small measure of shock isolation.
• Multiple mounting points: A mix of 1/4 and 3/8 threaded holes plus cold shoe and ARRI-style locating holes support microphones, arms and other accessories.
• NATO rail: Built-in NATO rail allows quick attachment and removal of compatible accessories including side handles for handheld shooting.

Who It's For

This cage is aimed at independent filmmakers and run-and-gun shooters who use the Blackmagic Pocket Cinema Camera 4K or 6K and want to expand their rig with handles, microphones, SSD mounts or lens support without blocking essential ports. The light weight and gimbal compatibility also suit creators using a Ronin S or Zhiyun Crane 2.

It is not for owners of the 6K Pro or users who need integrated power solutions out of the box; those buyers should look for a cage explicitly listed for the 6K Pro or a cage with included SSD and power mounts. Also, those who require full weather sealing or built-in electronics should consider alternative enclosures.

Pros & Cons

Pros

• Well built with plentiful screw holes, giving flexibility to mount accessories like an articulating arm or HDMI clamp.
• Lightweight design keeps overall rig weight down while still offering secure protection.
• Maintains access to battery and SD card so you can swap media without removing the cage.
• NATO rail enables fast accessory swaps and pairs with SmallRig side handles for handheld work.

Cons

• Not compatible with the 6K Pro, so buyers must confirm camera model to avoid fit issues.
• Some users report mixed fit on certain 6K G2 variants, so minor trim or adjustment may be needed.
