This Mount Plate from SmallRig attaches to the bottom of your Sony a7R VI using a 1/4"-20 screw and a locating pin. It has a rubberized traction pad and raised lip to prevent camera movement. The baseplate has an Arca-type dovetail for connecting compatible tripods or gimbals plus multiple 1/4"-20 threads for attaching small accessories. A QD quick release socket offers additional carrying options. A dedicated slot conveniently stores the included magnetic hex key, so it's ready to use right out of the box.
