The Zacuto 5in Z-Rail is part of our Blackmagic Top Handle. It is compatible with the Blackmagic Camera and other cameras and cheeseplates. It attaches via (2) ¼” 20 screws (included) that are spaced 3/8" screw center to center at their closest to 4 1/8" at their furthest. This longer Z-Rail is particularly helpful when using the Zacuto Axis EVF Mount with the Black Magic Camera so there is more clearance to adjust the EVF mount.
Zacuto dovetail accessories are adjustable to work with Z-Rail, NATO, SWAT, RED, PICATINNY, and WOODEN CAMERA rails.
