The Arca-Swiss C1 Cube is a three-axis panoramic head with an 88 lb load capacity, making it ideal for use with the heaviest cameras while maintaining a high degree of accuracy. The C1 Cube allows for finely-calibrated gearless panning adjustments with tension control.
The two panoramic axis permit you to first center the Cube's controls to your position with the bottom axis, and then readjust the camera to point straight ahead with the upper axis. The gears' rubberized knobs give pinpoint control even when wearing gloves, and don't obstruct the head's movements. On the bottom there's a hinge allowing 62°of tilt so that most cameras can reach the 90° vertical position. On top of the Cube there are two bubble levels and Arca-Swiss' Classic style with GP (Geared Panning) quick release clamp.
The Cube's is perfect when precise movements and adjustments are required. Its design allows far fewer focusing readjustments while creating images. It essentially places the camera inside a sphere, as if the axis met at a point upon the image plane itself, with the camera rotating around a stationary image plane. This engineering feat was achieved to minimize movements to the optical system's entrance pupil during composing, making for speedier field work free of perpetual height and focus adjustments.
