SmallRig 3667B Full Cage for Sony Alpha 7R V/Alpha 7 IV/Alpha 7S III/Alpha 1 / Alpha 7R IV
Custom-fit to select Sony a7 and a1 models, this Full Camera Cage from SmallRig protects your camera while providing a myriad of mounting points for customizable gear configurations. The design of the cage maintains access to the camera’s buttons and ports thanks to a hinged arm for battery replacement, among other custom details. Two locking side plates with M2.5 screws are interchangeable, depending on the camera model you are using, for extra security.
Multiple 1/4″-20 threads and ARRI anti-twist 3/8″-16 threads throughout the cage offer mounting points for articulating arms. Two cold shoe mounts and a NATO rail can accommodate wireless transmitters, fill lights, or side handles. The bottom of the cage features an Arca-type quick release plate for easy integration onto a tripod or stabilizer. The cage’s overall aluminum alloy and stainless steel construction creates a durable and lightweight design, and rubber pads on the interior protect the camera from scratches.
