With the Q=BASE NOVOFLEX presents a completely new type of a quick release - not squared but pleasantly round - for the popular ARCA-Type plates. Novoflex, for the first time, features automatic locking of the Arca plates on to the Q-Base. Precise final positioning of the plate takes place manually with a knurled base ring. This excellent combination of automatic locking function and manual adjustment gives the user an optimal check of the clamping function and allows, for the first time, one hand operation of an Arca compatible system! The system fits perfectly not only to the NOVOFLEX removable Q=PLATE but also to most other plates of similar design, the Q=BASE features a safety pin, to prevent inadvertent dropping of the equipment. Fast handling in connection with highest mechanical quality and a really beautiful design gives this patent protected quick release a technical top place under the systems of quick releases.
