Lightweight zoom and focus control options for broadcast HD lenses on camera stabilizers

16 years old. Gear and prices may have changed since.

What the thread found

  • The G-Zoom controller combines zoom and focus adjustment in a single compact unit and is described as reliable and smooth-operating.
  • Varizoom zoom-only controllers are bulkier and operate less smoothly than the G-Zoom.
  • Modern Fuji HD lenses feature 12-pin connectors for servo control on the lens, while Canon HD lenses use 20-pin connectors.
  • The G-Zoom is available in two variants: a BFD Edition with hardwired connection to BFD focus adapters, and a Custom Edition with universal connectors for multiple lens types.
  • G-Zoom units can be manufactured to fit within the approximately one-inch gimbal handle width of the Flyer stabilizer.
  • Manual focus adjustment becomes fatiguing during extended low-mode shooting without motorized focus control.
  • Libec offers zoom-only controls but does not include focus adjustment capability.
  • Varizoom does not offer combined zoom and focus control products.

Depends on

  • Stanton follow focus systems exceed the weight capacity of the Flyer stabilizer when mounted with necessary motors and bracketing.
  • G-Zoom availability and fitting for specific camera rigs requires direct contact with the manufacturer to confirm compatibility and obtain appropriate connectors.
  • The discussion primarily addresses lenses with internal servo motors rather than manual-focus glass.
