SmallRig Rotatable Horizontal-to-Vertical Mount Plate Kit for Sony a7R IV, a7R V, a7 IV & a7S III

SmallRig 4148 Overview
This  Rotatable Horizontal-to-Vertical Mount Plate Kit for Sony Mirrorless Cameras  from  Smallrig  is a faster and more versatile alternative to using a conventional L-bracket to mount select Sony mirrorless cameras to a tripod head. This lightweight rotating mechanism allows camera orientation to be changed with the flick of a wrist, then locked in place with a large, ergonomic knob. The plate mounts to the base of the camera, leaving the sides and back uncover for full access to the ports and LCD screen. The base plate also allows full access to the camera's battery door.
