We're going to discuss how this follow-focus system is different.
There is no gearbox and there are no ring gears. Instead, the focus wheel features a soft, high-tech O-Ring that presses up against a focusing ring of a lens, and thus pressed up adjusts focus when the focus wheel is turned. This efficient design means convenience in swapping lenses.
The iDC Photo Video SYSTEM ZERO Follow-Focus XL1 W/ Viewfinder & Camera Plate For Canon T2i is a set consisting of a focus wheel, an add-on viewfinder, a T2i-specific camera plate, and a seven-slot focusing plate. The camera plate attaches to the bottom of the T2i. The focusing plate attaches to the camera plate. And the focus wheel slides into one of the seven dovetail slots of the focusing plate. The viewfinder is iDC's modified version of the Hoodman HoodLoupe 3.0. It was adapted and modified for use with the included camera plate. The modification enables quick-release functionality and consists of a quick-release bracket permanently attached to the Hoodman HoodLoupe. Via the bracket, the viewfinder attaches to the camera plate by means of two red-handled screws. As a modified version, this viewfinder will not work without the included camera plate.
The O-Ring mentioned above is replaceable yet very tough. A thumbscrew on the focusing plate tightens to keep the O-Ring pressed up against a lens. When the thumbscrew is loosened, the focus wheel that the O-Ring is featured on can be moved aside, thus facilitating a lens swap.
Our set is compatible with a very long list of lenses (see specs) because the focusing plate by means of seven slots was designed to accommodate a variety of lens constructions. And for those lenses that fall in-between the dovetail slots, the focusing plate slides for quick micro-adjustments.
The included focus wheel can be used with all iDC camera plates and thereby with DSLRs other than the T2i.
Our SYSTEM ZERO set can be mounted onto any shoulder rig or quick-release plate that accepts 1/4"-20 or 3/8"-16 fasteners.
