The Camera Cage from SmallRig provides a variety of accessory-mounting options for your Sony a6000, a6300, a6400, or a6500 camera when it has the Meike MK-a6300/a6500 battery grip attached, and the a6500 with the Meike MK-a6500 Pro battery grip attached.
Constructed from lightweight yet durable aluminum, the cage incorporates multiple 1/4"-20 and 3/8"-16 threads, ARRI-style anti-twist mounts, NATO rails on top and on the side, an anti-twist M2.5 thread, and a shoe mount for mounting accessories. The cage maintains access to the camera's controls and ports when mounted on your camera, and it also provides access to the batteries in the battery grip. A flat head screwdriver that rests on the bottom of the cage is used for quick and convenient mounting and unmounting.
