Used CineMagic Revolution Lens System

Cine Magic International's new Revolution Lens System. It's the world's first snorkel lens system that allows live panning of the objective lens while maintaining a level horizon. The built in image orientation optics allow the image to be rotated to any position within a 360 degree circle. Spinning images can also be accomplished by continuously rotating the image rotation ring.
 

When using the Horizon Tracker module, the horizon can be set to the desired position and locked. This innovation allows the objective lens of the snorkel to be panned while the horizon remains in the level or dutched position that you have chosen. A six or seven inch diameter is all that is needed to achieve the 360 degree pan making this device ideal for tabletop or miniature shots!
 

The Dual Swivel module adds a second pan axis to the lens system. In this case, the horizon lock is not used. The horizon can be adjusted manually or electronically. The Preston FI+Z focus system available at CamTec, can be programmed to automatically correct the horizon while panning with the Dual Swivel module.
 

This ability to control the horizon angle while aiming the camera and snorkel at any angle, in any direction, gives the Revolution a distinct advantage over previous snorkel systems that limit the control over camera movement in order to maintain the horizon line. Whether using the Horizon Tracker module or the Dual Swivel module, infinite shooting angles can be achieved without requiring specialize and time consuming rigging equipment.
