The Chrosziel StudioRig Cine is a professional single-sided follow focus for precise focus actuation on high-end cinema lenses. The single-sided design of this StudioRig Cine features a low-profle rod-clamp form factor for fitting underneath large lenses. However, as it is only single-sided, the entire follow focus must be reattached to adjust focus from the other side of the lens.
Once the follow focus is clamped down on the rods, swing the arm to engage the drive gear to the lens. Drive gears are available separately from the StudioRig unit. The Varilock handwheel lets the operator set focus in and out points for consistently repeatable focus moves that can be made without looking at the marking disk. A white dry-erase marking disk and focus crank are included with the follow focus.
