What the thread found

• The Red Rock Micro follow focus system uses an iPhone or iPod Touch as a display interface showing focus position on a rotating wheel, depth of field visualization, and sonar autofocus data, while the wireless radio function remains in the control unit itself.
• The system stores focus ramp settings and lens calibrations and can display iris control via screen sliders while the wheel controls focus.
• A complete wireless single-channel setup with motor receiver and measuring tool was estimated to cost between $3500 and $5000, while a hardwired controller alone was estimated at around $1000 and the measuring tool at $500.
• The system was not fully functional at NAB, with latency issues and the sonar autofocus feature not working reliably at the time of demonstration.
• The system is designed only for compatibility with analog motors, not digital motors.
• The wireless frequency range had not been finalized and no FCC clearance had been obtained at the time of the discussion.
• Multiple wireless receivers can be controlled from a single hand unit for multi-channel setups.

Depends on

• Prices and specifications were estimates based on early conversations; final pricing was unclear and dependent on demand and production decisions.
• The sonar autofocus feature was not functioning properly during demonstrations.
• Radio frequency details were unconfirmed and FCC approval was still pending.
• The technology was in early development with multiple design revisions over several years before this NAB showing.
• Some participants expressed concerns about using an iPhone as a control interface in professional production due to potential interruptions from phone calls.
• The system felt less refined compared to established high-end follow focus manufacturers.
