V3 with grip and PZ-130 mounted on my tripod
The combination feels very securely mounted. I have placed the PZ-130 plate so the anti-twist flange is behind the back edge of the grip, and with the ¼” screw in the side slot to reposition the plate as close to the optical centre as possible. It’s not perfect aligned in the optical centre, approximately 6mm off (0.24”). The grip’s mounting screw knob is not disturbed by the plate position.
