SmallRig 4161 Overview

Provide accessory mounting and protection for your Canon EOS R6 Mark II camera with the lightweight aluminum "Black Mamba" Camera Cage from SmallRig. This formfitting cage features a sleek, rough-black finish with carbon fiber-style details, it maintains access to the camera's controls, battery, and SD card slot, and it features a variety of mounting options.

The camera mounts onto the cage using a 1/4"-20 screw, two side lock adapters, silicone padding, and a front lip to prevent the camera from twisting. In addition to multiple 1/4"-20 and 3/8"-16 accessory threads, the cage features ARRI-style locating holes to prevent accessories, such as an optional top handle or HDMI cable clamp, from twisting when mounted on the cage.

The cage features an integrated Arca-type mount on the base, so you can mount it onto standard Arca-type heads and bases. There is a shoe mount on top for an accessory, and integrated strap slots and a QD mount allow you to add a separately available wrist or neck strap. A magnetic screwdriver for securing the camera screws is included and stores in the base.

Very durable and keeps my camera protected. Would absolutely recommend.

Feels like a body protector with good ports for future items to be attached. Easy to install, and the weight is bearable or light. Nothing is obstructing any buttons or dials with this cage. Worth the buy.

Does this fit the R6 mark iii?
Asked by: Raeis
It may not be specifically designed for the R6mk3 but I’ve tried it and it does fit. Getting it on and off the R6mk3 feels a little more difficult than it did with the R6mk2, but it seems to be just fine.
