The PZ-17 Camera Plate for Sony Alpha a9, a7R III, a7 III, and Fujifilm X-H1 from Kirk Enterprises is designed with a 90° anti-twist lip, which keeps the camera body from twisting while mounted on an Arca-type ball head or clamp. Moreover, once the dovetail plate is attached to the camera, it gains a quick release functionality.
The 6061-T6 aluminum plate maintains complete access to the battery door, and does not obstruct the tilting LCD monitor of the camera. Also, the plate has been black anodized, which makes it resistant to scuffs and scratches.
A boss has been machined into the side of the plate for an accessory hand or shoulder strap. Optional safety stops, which prevent the camera from falling out in case the clamp is partially open, can be added to the bottom the plate. Plus, the rear of the plate has been scored with a sensor centering lines for alignment of the camera.
