Really Right Stuff multi-use plates are designed for some camera bodies and are precision machined from solid blocks of 6061-T6 aluminum. Fully compatible with any RRS Dovetail style quick-release system, our plates feature simple square anti-twist flanges that prevent twisting between the plate and the camera body. This quick release plate utilizes a custom machined 1/4″-20 threaded, captive-style mounting screw that threads into the tripod mounting socket of your camera body.
