The NOVOFLEX Q=Plate series QPL-VERTIKAL is an "L" shaped bracket plate that enables a fast changeover from the standard horizontal position to a vertical picture mode. The plate also works with a power booster or vertical grip attached to the camera. Fits on the NOVOFLEX 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.
