J-7 follow focus zoom control malfunctions during live shooting

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

What the thread found

  • Uncontrolled zoom movement on a J-7 connected to a Canon 8-pin lens can result from cable wiring issues or disconnection at the connector junction where the cable enters the device.
  • A loose or unsoldered wire inside the J-7, particularly one related to VTR or run functions, may cause intermittent zoom activation.
  • The J-7 experienced reliability issues with newer digital lenses and had problems with zoom creep.
  • Cable routing around gimbal connections is subject to kinking and twisting that can damage internal wiring over time.

Depends on

  • The reported problems were from 2006 equipment that has since been discontinued.
  • The exact cause of the malfunction was not definitively confirmed in the discussion.
  • One participant's experience with the J-7 came from approximately three years prior to their post, representing older usage data.
