What the thread found

• Early J7 zoom control units were available in versions with different pin-out configurations for Canon and Fuji lens compatibility
• All J7 units included pressure-sensitive sprung potentiometers for speed control rather than requiring manual pot adjustment on the lens servo
• A common maintenance issue with J7 units was centering drift that could be addressed by drilling access to the trim control without full disassembly
• Zoe III from Bebob was suggested as a modern alternative pressure-sensitive zoom rocker option with auto-sensing between different connector types

Depends on

• The thread does not provide repair cost estimates or definitive recommendations on whether repair is economically justified
• No clear answer was given about current availability or where to purchase J7 combo units
• The exact technical specifications distinguishing different J7 variants were not fully detailed
