The G-ZOOM device with Fujinon connectors can operate zoom and focus functions remotely when a focus servo motor is installed in the lens.
G-ZOOM has been reported as effective for simultaneous zoom and focus control by a single operator over a period of several years.
The cables connecting to G-ZOOM are very thin and require careful handling to prevent damage.
Customer support from the G-ZOOM manufacturer is reported as responsive.

The G-ZOOM solution works only if the lens already has a focus servo motor installed.
One user's positive experience spans five years but represents individual experience rather than comprehensive testing.
The employment practice of operating without a dedicated focus assistant is contested in certain regional broadcast markets where union or industry standards expect dedicated crew positions.
No information provided about performance differences between remote focus control and dedicated operator in live broadcast versus tape scenarios.
