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 With Camera Plate For Panasonic GH2 is a set consisting of a focus wheel, a GH2-specific camera plate, and a seven-slot focusing plate. The camera plate attaches to the bottom of the GH2. 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 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 broadly compatible with many lenses 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 GH2.
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.
