The Elements Micron BridgePlate is one of two components that make up Elements's Micron Standard, designed to provide a non-bulky and lightweight support system for larger-sized digital cameras like the Epic, C500, and FS700. The other component is a Micron Dovetail, sold separately. The Dovetail is natively compatible with OConnor's 1030D and 1030DS heads and with Sachtler, Cartoni, Miller and Manfrotto quick-release plates. And the BridgePlate just as natively slides right onto the Dovetail. The BridgePlate accepts 15mm rods, and since attachment to a tripod is by way of a Dovetail, the rods would be completely free for a follow focus, matte box, and other accessories.
