B3 lens wiring diagram
 

Anybody got one? I can't find this info anywhere...I have gotten an old Ikegami 13X Canon with a 2X multiplier to work optically on my Nikon 1 camera and I want to wire up the electronic zoom - B4 Hirose to DC adapters don't work - B3 lenses are wired differently than B4 lenses.

Amongst my collection of my "I'll keep that info it may be useful one day." file I found the following. The pin outs listed are for a Canon J8 B3 (Ikegami mount) 12 pin Hirose connector.

As always proceed with caution as I haven't checked these personally so I cannot verify any results from using the following wiring pin outs. All care but no responsibility as the airlines say!

Pin 1: +ve
Pin 2: -ve
Pin 3: Gnd
Pin 4: VTR
Pin 5: RET
Pin 6: ID/CO (Iris control)
Pin 7: IE/IND (Extender indication)
Pin 8: AT/RM (Iris remote selection)
Pin 9: AT/MA (Iris manual selection)
Pin 10: P.P
Pin 11: Z/IND (Zoom position indication)
Pin 12: F/IND (Focus position indication)
