Sony A9 Modular Plate

Overview

The BA9 plate system is compatible with the Sony A9, A7III, and A7rIII

Really Right Stuff camera body plates are all custom designed for each camera body and precision machined from solid blocks of 6061-T6 aluminum. Fully compatible with 1.5" RRS dovetail standard, our plates feature precisely contoured anti-twist flanges for a perfect fit that prevents twisting between the camera and our plate. All of our quick-release plates utilize a custom machined 1/4"-20 threaded, captive-style mounting screw that threads into the tripod mounting socket of your camera body. As part of a modular system, this conventional base plate still functions as a traditional camera mounting plate, but also has the added flexibility of accepting a separate dedicated vertical L-Component to create a fully modular L-Plate with two dovetail mounting surfaces. You can purchase the dedicated vertical L-component as a separate add-on, or as a set package with the base plate.
