The PZ-158 Camera Plate for Nikon Df from Kirk is a quick-release plate that is designed for use with the Nikon Df DSLR. It fits Arca-type clamps to enable a quick release from a tripod head. The plate is machined in the USA from 6061-T6 aluminum alloy and features a 1/4"-20 stainless steel hex screw for attachment to the camera. There is also a second 1/4"-20 socket adjacent to the screw. Two hex wrenches are supplied to tighten the camera screw and the safety stop screws. The side of the PZ-158 plate features a sensor-centering line to help you properly align your camera.
