Wireless follow focus system selection and compatibility with Steadicam Zephyr

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

What the thread found

  • The Hocus Focus system works with Steadicam Zephyr but has a motor too weak for large cinema lenses.
  • Hocus Focus motors are not compatible with other manufacturers' motors.
  • Industry-standard wireless focus systems are Bartech Focus Device and Preston systems.
  • Bartech systems are known for being rugged and reliable at lower cost compared to Preston.
  • Preston systems offer multi-channel control for focus, zoom, and iris functions.
  • Used analog Bartech systems with analog motors represent the cheapest option for cinema lens compatibility.
  • Used digital Bartech systems are the next price tier above analog models.
  • A power cable from the Steadicam sled is needed to power the receiver unit.
  • Start-stop cables are convenient but not mandatory for operation.
  • A rod system or 15mm rod bracket is required to mount the focus motor on the camera.

Depends on

  • Hocus Focus Pro was announced as new and unproven at the time of discussion.
  • Compatibility between wireless focus systems and camera types varies by lens size and type.
  • Multiple system options exist but most alternatives to the major brands should be avoided.
  • Exact compatibility details between specific focus systems and Steadicam Zephyr power connections need verification.
