What the thread found

• The VFX focus/iris controller used Heden motors and was powered by a 9V battery.
• The manufacturer of the VFX system ceased operations around 1999 to 2000.
• Support and availability for VFX controllers had declined significantly by 2010, making them less practical as primary systems.
• Repair services for VFX units may have been available through third-party shops, though this required verification.
• Alternative options like BFD and Preston systems were considered more reliable choices for backup focus control equipment.

Depends on

• The discussion reflects conditions in 2010, a decade after the manufacturer ceased business.
• Exact current availability of repair services was uncertain and required confirmation at the time of discussion.
• The comparison to other brands like Preston and BFD is based on individual user preference rather than comprehensive testing.
