Digital follow focus systems with self-calibration have difficulty tracking continuous focus rings on lenses without hard stops, as motors tend to overshoot small resistance points.
Lenses with hard stops such as Zeiss ZE, Zeiss CP2 prime lenses, Zeiss LWZ, and older Tokina models provide better compatibility with digital follow focus systems.
Digital systems featuring lens mapping functionality allow operators to create reference points by taping focus positions against a measure, enabling software interpolation across the focus range.
An iris slider add-on accessory works with both analog and digital receivers for focus control, but requires a digital receiver specifically for iris control.
Analog follow focus receivers can be modified with an internal voltage switch to operate lightweight focus motors designed for ENG lenses at reduced power levels.
The G-Zoom Bartech controller works exclusively with analog follow focus systems and receivers.
For broadcast TV lenses, a complete wireless focus control setup can be built using an analog receiver, a Stanton focus motor with appropriate gear ring, the Bartech small focus controller attached to a gimbal handle, and appropriate motor mounting brackets.
