Rocker-style zoom controls for Steadicam follow focus systems and mounting modifications

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

What the thread found

  • Rocker-style controls provide better feathering and easier pressure control than pressure-sensitive zoom systems when used with gimbal-yoke Steadicam rigs.
  • A microphone clamp can be used as an alternative mounting bracket for zoom units like the ZOE, replacing the standard long screws with recessed screws, offering a cleaner and more secure connection with easier attachment and removal.
  • The ZOE III produces smooth zoom response with variable speed control and improved feathering compared to earlier ZOE models.
  • Using focus or iris sliders for very slow zoom movements can work but produces inconsistent results and is more difficult to execute than dedicated zoom units with tachometer motors.
  • Zoom performance quality varies based on the motor type used: tachometer motors provide more consistent speed control compared to potentiometer motors.

Depends on

  • The ZOE III compatibility with the rocker-style system was not definitively tested at the time of discussion.
  • The microphone clamp mounting solution's performance depends on the specific gimbal handle type and grip material used.
  • Very slow zoom movements using iris or focus sliders are difficult to execute well and results depend heavily on operator skill.
  • The ZOE's cable design was noted as problematic and needed replacement.
