The SYSTEM ONE Follow-Focus Kit with One Wheel for Canon 7D Without Grip from iDC Photo Video is a tripod-based, gearless, follow-focus and support system designed for a Canon 7D. This dedicated system is specifically fitted for a 7D and features perfect primary balance, a very low center-of-gravity, great adjustability, and minimal mass. No quick-release plate is required--the UniRail can be longitudinally positioned for perfect primary balance with any camera, lens, and accessory configuration.
The gearless direct-drive focusing wheel is machined from industrial plastic bearing material and has a soft high-tech O-ring for positive rubber-on-rubber operation. The iDC UniRail features a double-dovetail design. For the lowest possible center-of-gravity, the UniRail's lower dovetail is compatible for direct mounting into the quick-release clamps of select Gitzo, Manfrotto and Sachtler heads. It also features a centralized QR Base Pad that offers both 1/4"-20 and 3/8"-16 threaded bosses to fit any fluid head. This simple and efficient follow-focus system is a finely-tailored, elegant HD filmmaking platform that can be easily upgraded with a wide variety of superb iDC accessories. And, it's made in the USA.
