The CASTEL-CROSS MC focusing rack was developed in response to customers who have been looking for a professional solution for spot-on positioning of a camera in two directional axes. The CASTEL-CROSS MC focusing rack allows highly sensitive and smooth adjustment of the camera in the X and Y directions, without loss of stability and accuracy. The CASTEL-CROSS consists of 1 CASTEL-Q, 1 CASTEL-L and one 1/4 inch camera coupler. The bottom rail is dovetailed its entire length allowing it fit into any Arca compatible mount, The focusing rack is constructed to be maintenance free, no special care is required. Make sure not to oil the rails as this will attract dust and dirt that will clog the gear teeth.
