The Push-Button Viewfinder Mount is designed with a 15mm rod with push-button and a L-bracket viewfinder clamp with ratchet knob. The 15mm rod is compatible with the Canon EOS C500 Mark II camera handle or any 15mm mounting hole. It features two points of articulation for horizontal, vertical, and transversal adjustment of your viewfinder. By simply pressing the SHAPE patented push-button, you are allowed a 360-degree rotation to place your view finder in the best position for your use. Push, adjust, release, and then its lock.
