The custom Camera Plate for Sony Alpha 1, a9 II, a7R IV, and a7S III Camera with VG-C4EM Vertical Grip from Kirk is compatible with Arca-type quick release systems, but also provides the option of mounting the plate onto a tripod or bracket via its 1/4"-20 mounting socket. The anti-twist flanges on the plate hug the vertical grip to prevent any movement while mounted, and the QD quick disconnect system socket allows a compatible strap or harness to be attached.
