Protection measures for digital video lens interfaces against hot-plugging damage
19 years old. Gear and prices may have changed since.
What the thread found
- Canon and Fujinon digital lenses can suffer circuit board damage when a Micro Force is connected while the camera is powered on.
- Installing an optical isolator circuit board in the Micro Force prevents damage by delaying the zoom signal until all connector pins make contact.
- Video cables must have a protective transistor installed, indicated by a green band on the lens connector end.
- Older Micro Force or V+F control units may not be configured for video lens operation despite having a model designation suggesting video capability, requiring verification before use.
Depends on
- The advisory targets Micro Force V+F2 and Digital Micro Force models specifically, with different guidance for older models.
- The cost of circuit board repair is noted as substantial but no specific figure is provided.
- Discussion includes joking comments that do not reflect genuine technical concerns.
- No information about connector variations across manufacturers or within manufacturer product lines is conclusively addressed.
