New, unused. Immediate purchase OK. This Dual-sided Cine Follow Focus features a 1:1 handwheel to gear ratio for incredibly precise focus pulls. The dual-sided design allows you to adjust the lens's focus from either side of the camera. It attaches to both 15mm LWS and 19mm rod supports by snapping onto the rods. This allows you to adjust, attach, and detach without removing other accessories (like matte boxes or lens supports) that are mounted on the rods. The gear is mounted on a swivel, allowing it to be rotated against the lens for a snug fit. The entire unit can also be slid left or right, making it easy to adjust for any size lens. 【Technical Data】 Weight: 3 lbs Color: Black Material: Aluminum-alloy, stainless steel Rod System: 15mm LWS/19mm studio
