SmallRig Full Camera Cage for Blackmagic Design Pocket Cinema Camera 4K & 6K (New Version) 2203B is a form-fitting cage. It is securely locked to the camera by 1/4"-20 screws on the top and bottom, with additional locating pins and rubber pads on the base plate preventing wiggles and scratches. On the top and left side of the cage are built-in NATO rails, where you can attach SmallRig NATO Top Handle 1955 or SmallRig Wooden NATO Side Handle 2187 for hand-held shooting. Multiple 1/4"-20 & 3/8"-16 threaded holes and ARRI locating holes are designed to attach accessories, such as SmallRig Ballhead Arm 2070. For users who record videos, a Samsung T5 SSD Mount 2245B would be a good choice. The cage is compatible with SmallRig HDMI & USB-C Cable Clamp 2246B to fix the cables. It works with SmallRig Metabones Adapter Support 2247 on BMPCC 4K to keep your lens stable. Besides, a built-in hex spanner is provided on the bottom plate.
