The Stroboframe QRC is a compact, low-profile quick release that automatically docks and locks your camera or bracket to a tripod. It"s also perfect for use with studio stands and copy stands. The entire system consists of a QR Receiver mounted to the tripod, and a QR Plate attached to the camera. (Many of our brackets have an Integral QR Plate already built in). Just lower the camera or bracket into the QR Receiver and push down... your camera is mounted and securely locked into place. To remove the camera or bracket, squeeze the QRC"s lever and lift out! The system is fully compatible with all 35mm and medium format cameras, you can use Camera Anti-Twist Plates. QRC systems are available as complete kits, including a QR receiver and/or QR Plate, or, you can purchase the QR Receiver alone for use with Stroboframe brackets that have Integral QR Plates. Standard QR Plates are also sold separately. The unique QRC Quick-Release system has many other applications. Use it with copy stands for faster, convenient film reloading without disturbing the setup, or for mounting spotting scopes for birding and target shooting. Skydivers even use them to mount cameras on their helmets!
