iPhone-based iris control system for cinema cameras via wireless connection

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

What the thread found

  • A wireless control system can operate cinema camera iris and zoom functions through an iPhone or iPod Touch interface using WiFi connectivity.
  • The control interface allows users to set operating range limits by dragging fingers apart or together on the screen, restricting adjustments to only the desired range.
  • The system supports landscape mode display of up to three cameras simultaneously and portrait mode selection of individual cameras.
  • The control unit works with multiple motor brands including Preston and Scorpio systems and should function with any digital camera motor.
  • The MDR receiver unit is physically smaller than a Preston HU3 battery charger.
  • Using airplane mode with WiFi enabled on the control device prevents unwanted network interruptions during operation.
  • Tactile feedback is absent compared to traditional mechanical focus pullers, requiring visual confirmation on screen rather than relying on muscle memory for precise adjustments.
  • Noticeable latency exists in the wireless transmission, similar to older commercial follow focus systems.

Depends on

  • The application was not released to the general public at the time of discussion, limiting widespread testing and feedback.
  • Touch screen input lacks the tactile feedback that professionals depend on for precise iris and focus adjustments by feel alone.
  • Operating via touch screen requires constant visual monitoring between the device and the camera action or monitor, unlike traditional mechanical controls.
  • WiFi-based operation can be interrupted by cellular network interference unless manually disabled.
  • The system introduces transmission delay comparable to older commercial wireless follow focus equipment.
  • Practical suitability for fast-paced production work like Steadicam operation remains unproven.
