SmallRig has hundreds of available accessories for a variety of cameras. Need a baseplate for a RED or cheese plate for a Panasonic AU-EVA-1? They've got them both, and the best part of all, the products are very budget-friendly. The other nice thing about the company is they allow anyone to submit ideas for production. If they adopt it, you receive one for free and get design credit.
Such is the case for the SmallRig Camera Cage for BMPCC 4K and 6K with Battery Grip designed by Yetta White. The Blackmagic Design Pocket Cinema Cameras are some of the most popular image capture devices around, but one of its biggest flaws is battery life. It has improved since the original Pocket Cinema Camera, but using the optional battery grip for the BMPCC 6K/4K is the way to go. It's powered by two Sony L-series batteries and mounts on the bottom of the camera providing around 2 hours of runtime, which is about double the time when using the native battery alone.
This is where the SmallRig cage comes in as it accounts for the extended footprint. The cage is formfitting and lightweight. It secures to the camera via a 1/4-20" screw on top and 2 on the bottom while still providing full access to the camera's control and ports. The cage also provides access to the batteries in the vertical grip so there's no need to remove the cage when replacing a battery.
The cage has multiple 1/4"-20 and 3/8"-16 threads, ARRI-style twist mounts, 2 NATO rails, and 3 cold shoes for accessories where you can attach a microphone, monitor, cable clamps, matte box, or follow focus. The cage also provides slots for neck straps. It's designed out of durable aluminum alloy and well-priced at only $69. The company is accepting pre-orders now with an expected ship date of mid-July. SmallRig also has an option available without the battery grip for $79.
