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 any standard 1.5"-dovetail style quick-release system, 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.
