iPhone-based follow focus control system for iris and focus motors

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

What the thread found

  • The system operates as a direct wireless connection between the transmitter device and receiver, functioning as an ad-hoc network without requiring a separate WiFi router on set.
  • An iPod Touch is preferable to an iPhone as the primary transmitter to avoid interruptions from phone calls or accidental airplane mode activation.
  • The system was designed by someone with experience in wireless controls for cinema equipment and performed reliably during exhibition demonstrations.
  • A physical knob attachment that connects through the docking port was planned to be released within a few months of the discussion.
  • The device is compatible with any digital motor and can be used for iris control.
  • Charging the transmitter device before shooting is necessary.

Depends on

  • No detailed real-world field reports on dropout rates or reliability issues were provided in the discussion.
  • No information was given about range limitations or interference susceptibility in outdoor locations.
  • The system's compatibility with specific professional focus control systems like Preston was not confirmed.
  • Discussion took place in 2010 and product availability status outside Europe was unclear at that time.
  • Claims about reliability were based on limited demonstration experience rather than extensive production use.
