How to Rig a Blackmagic Pocket Cinema Camera 4K

Quick Answer

Rig your Blackmagic Pocket Cinema Camera 4K by mounting it in a SmallRig cage, then adding a top handle, external battery solution, and a follow focus. This guide walks through each step with practical tips to avoid common build errors.

Step-by-Step Rigging Process

1. Mount the Cage: Place the BMPCC 4K into the SmallRig cage, aligning the bottom plate with the camera's tripod thread. Tighten the central screw with a hex key until snug — do not overtighten, as this can strip the camera's thread or warp the cage. Check that all cutouts for ports and buttons align before tightening fully.
2. Attach a Top Handle: Use a 1/4-20 screw to attach a top handle to the cage's top rail. Position it so your hand sits naturally above the camera's center of gravity. A common mistake is placing it too far forward, which makes the rig front-heavy. Test the balance by holding the handle with a lens attached; adjust position if the rig tilts forward.
3. Add External Power: Mount a V-mount battery plate or NP-F battery adapter to the cage using a 15mm rod system or a dedicated bracket. Connect the power cable to the camera's DC-in port. Secure the cable with a cable clamp or velcro tie to prevent accidental disconnection. Use a dummy battery or DC coupler rated for the BMPCC 4K to avoid voltage mismatch.
4. Install a Follow Focus: Attach a follow focus unit to a 15mm rod that slides into the cage's rod mount base. Align the gear with your lens's focus ring. If the gear slips, add a rubber ring or adjust the tension screw — a loose gear causes missed focus pulls. Ensure the follow focus does not block access to the lens release button or the cage's side handles.
5. Cable Management: Route the HDMI and power cables along the cage's frame using cable clips or velcro straps. Keep cables away from moving parts like the follow focus gear. A tangled cable can yank the HDMI port, a known weak point on the BMPCC 4K. Use a right-angle HDMI adapter to reduce strain on the port and keep the cable flush with the cage.
