They call it iDC System One. Check it out at PhotoPlus Expo in New York, October 28, 29, 30 — in the Video Pavilion, Booth #562. System One is the latest big idea from iDC Photo Video. Rails instead of rods. They’re standard Manfrotto/Gitzo dovetail size–so they slide right into your tripod head without having to bolt on additional plates. Director/Cinematographer/Photographer/Explorer of Light and Master of the HDSLR Universe Bruce Dorn has come up with a major improvement on his already excellent gear-less Follow-Focus system for HDSLR cameras.
In early 2009, Bruce took his 30 years of Hollywood filmmaking experience and took a fresh look at follow-focus systems for the newly-released Canon HDSLR cameras. The result was the original iDC Run & Gun, the industry’s first friction-drive, gear-less follow-focus system.
Bruce’s latest design, the modular iDC System One, expands on that original concept and uses a sliding clamp system that lets you quickly and easily position the iDC friction-drive follow-focus, camera, and wide variety of HDSLR accessories. It’s designed for the following cameras:
- Canon 1D MK IV
- Canon 5D MK II with the BG-E6 Battery Grip
- Canon 7D with the BG-E7 Battery Grip
- Nikon D3s
Kits for non-battery grip versions of the Canon 5D MKII, 7D, and 60D camera bodies will be available soon.

iDC System One is built around the iDC UniRail—with its Double-Dovetail design for almost infinite adjustability. The position of both the camera body and the gear-less follow-focus assembly can be easily adjusted and balanced by sliding one way or the other. The Gitzo/Manfrotto fluid-head-friendly quick-release UniRails are available in four lengths: 6, 9, 12 and 16 inches. The bottom dovetail of the UniRail snaps directly into the quick-release top of many Gitzo/Manfrotto fluid heads, while also providing industry-standard 3/8”-16 or 1/4”-20 threaded mounts.
The top dovetail of the UniRail is machined to be “Arca-Swiss” compatible and supports the iDC Gearless Follow-Focus and accessories.
Three kits, with different lengths of UniRails, and single or multiple Follow-Focus Wheel Assemblies are available. Or, you can build a custom kit with à la carte options. Each configuration of the iDC System One requires only a camera-specific baseplate, which is available as an add-on option.
The iDC System One Viewfinder Assembly is available for the Canon 1D MKIV. Additionally, iDC System One will accept any Viewfinder system that mounts directly to the camera’s LCD without a camera plate requirement. iDC System One components are elegantly machined in Arizona from ultra-light aluminum with a Mil-Spec black-anodized finish.
The iDC System One Gearless Follow-Focus 6 inch Kits start at $599. For more info about iDC’s Essential Accessories for Stills and Motion, go to: www.idcphotovideo.com
