With the Velbon QRA-4 quick release adapter, you can quickly and securely attach your camera to the tripod with one hand, saving you the hassle of screwing and unscrewing. This is particularly practical for anyone using multiple cameras or a photo camera and a video camera on one tripod. The camera plate (QB 42) is easily attached to the bottom of the camera with a grippy screw, so no coin or similar tool is required. Depending on the camera or lens, the quick release plate can be mounted in two directions on the adapter. The round, highly visible leveling bubble allows for precise camera alignment. With the quick-release lever, you can secure the camera plate quickly and reliably every time. Lightweight and compact, thanks to the magnesium alloy used, the QRA-4 quick release adapter is especially suitable for mirrorless cameras and smaller camcorders.
