The NOVOFLEX Q=Plate series QPL-VR PRO is an "L" shaped bracket plate that enables a fast changeover from the standard horizontal position to a vertical picture mode. In addition, this plate is especially ideal for panorama and VR use since it also has calibrated scales etched onto the sides of the plate, allowing for precise and repeatable positioning. Fits on the Q=BASE II and Q=MOUNT quick release adapters, as well as on any Arca-type quick release assembly. Note: The NOVOFLEX Arca-type quick release plates are thinner by the slimmest of margins than Arca-Swiss quick release plates. They are not recommended for use in the Arca-Swiss Flip-Lock quick release clamp.
