The Hand Crank HC-1 can be used with any 435 Xtreme or 435 Advanced (even without FEM-2), to achieve that old fashioned hand cranked look. An ARRIHEAD hand wheel (not included) can be attached to the HC-1, and the rotation of the hand wheel will govern the speed of the camera. The slight inconsistencies in speed introduced by the human arm is what makes for that special historic look in old newsreel footage, and it can now be re-created easily with the 435. To set the HC-1 to the operators liking, a fluid dampening of the hand wheel can be set, and three gear ratios can be programmed on the camera's display: 5, 10 or 20 frames per revolution. The HC-1 can control speeds from 0 to 150 fps, forward or reverse.
