The CASTEL-XQ is a heavy-duty focusing rack for macro photography with Arca-compatible connections and unique two-way quick release camera mount. The rack is very flexible in its possible uses: the quick release can be removed, and because the profiling of both the top of the main rail, and the base mount, is Arca-pattern, it can be used in combination with many Novoflex and other manufacturers' products. The special design of the Q-MOUNT XD clamp allows the camera plate, or a second focusing rack, to be fixed in either direction, with just one locking knob. Despite being only 250mm long, the CASTEL-XQ allows 375mm of camera movement. Weight 675g. Multiple 1/4" and 3/8" base sockets.
