The Really Right Stuff BA7RIV-B camera body plates are all custom designed to make the most secure fit as possible on both the Sony A7R IV and A9 II. Each plate is precision machined from solid blocks of 6061-T6, aircraft grade aluminum.
The Sony A7R IV-B camera plate is fully compatible with any standard 1.5"-dovetail style quick-release system. The plate is also has contoured anti-twist flanges for a perfect fit, which prevents twisting between the Sony A7R IV or A9 II cameras and custom plate. The BA7RIV-B 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 BA7RIV-B 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 it is included in the L-Set.
