Really Right Stuff L-Bracket for Sony Alpha a1, a7R IV, a7S III, and a9 II

The Really Right Stuff BA1 camera body plates are custom designed for the most secure fit as possible on the Sony Alpha-1, A7RIV, A7SIII, and A9II. Each plate is precision machined from solid blocks of 6061-T6, aircraft grade aluminum.

The Sony A1 camera plate is fully compatible with any standard 1.5"-dovetail style quick-release system. The plate also has contoured anti-twist flanges for a perfect fit, which prevents twisting between the cameras and plate. The BA1 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, the BA1 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.

The BA1 plate system is compatible with the Sony A1, A7RIV, A7SIII, and A9II.
