The PZ-163 Camera Plate from Kirk Enterprises is a quick release plate designed specifically for use with the Pentax K-1 DSLR. The integrated Arca-type dovetail enables compatibility with most Arca-type systems, including tripod heads and shoulder rig clamps. The plate features a 1/4"-20 stainless steel hex screw and an adjacent 1/4"-20 threaded socket. The side of the plate features a sensor-centering line to assist with proper camera alignment, particularly useful when photographing panoramas. The PZ-164 plate is machined in the USA from lightweight aluminum alloy and includes a hex key.
