Gear pitch specification for Fujinon ENG lens iris ring control

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

What the thread found

  • The iris ring on Fujinon ENG lenses uses a 0.4 gear pitch for follow focus control
  • Wireless iris control requires appropriate gears matched to the lens specifications
  • Iris pull responsibilities should be assigned to camera department personnel rather than the focus puller

Depends on

  • The specific Fujinon ENG lens model shown in the original image is not identified by model number in the thread
  • Gear availability varies by motor system and rental inventory
  • Discussion references older motor systems from around 2013 which may have different specifications than current equipment
