The SYSTEM ONE FF/VF Master Kit for Canon 5D Mark II (No Grip) from iDC Photo Video is a tripod-based gearless follow-focus and support system designed for a Canon 5D Mark II. All the tools you need for a fully functioning follow-focus rig are included: dedicated camera plate, two follow-focus wheel assemblies, four UniRails, two lens braces to support long lenses, three sliding risers for the follow-focus wheel or lens brace, plus all the hardware you need.
This dedicated system is specifically fitted for a 5D Mark II, and features perfect primary balance, a very low center-of-gravity, great adjustability, and minimal mass. No quick-release plate is required--the UniRails 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 Gitzo-, Bogen-, and Manfrotto-compatible for direct mounting into their quick-release clamps.
This kit also features a centralized QR Base Pad that offers both 1/4"-20 and 3/8"-16 threaded bosses to fit any fluid head. Four UniRails are supplied with this kit: 6", 9", 12", and 16". 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.
