The D/Focus Systems D/Mount V4 Bundle for Follow Focus and DSLR is a new design that utilizes a sliding baseplate to adjust the D/Focus similar to a rail system, but in a smaller, more dedicated package. The V4 is far more robust and reliable than any of the previous versions and will lock down firmly and not come loose under normal use. The D/Mount Bundle comes with the D/Mount V4, D/Focus V3, and a D/Gear Pro Lens Gear.
