Does anyone knows where 1,2,3,4 points on a zoom pot connect to a, A,B,C,D,E,F,G,H, CANNON lence connector for cannon lenses.
And also the same question with the same connector for fuginon lenses?
I know the start on off possition but I had a break down-someone riped off the cable by stepping on it - and I ergendly now need the wiring cause I use it every day?
Maybe Jim Bartell or anyone?

According to my records..............
HIROSE 12-pin:

1 = POT +
2 = POT -
4 = WIPER
9 = VTR run
10 = VTR run

TAJIMI 8-pin: FUJI

A = POT +
B = WIPER
C = POT -
E = VTR run
F = VTR run

TAJIMI 8-pin: CANNON

A = WIPER
B = POT +
C = POT -
E = VTR run
F = VTR run

Um....no. The TAJIMI (not HIROSE) connector has a threaded ring at the end, and is used on CANNON as well as FUJI lenses


I don't understand what you're asking here. I was just telling you what functions where active to the contacts on the connectors.

As I ve had already apologized to Fred for the confusion , The zoom controller pot is from an external zoom controller that connects with a cable to the tajimi connector under the cannon lense.
I have shorted E, and F possition on the tajimi connector that they appier to be the camera start on off.
All I need now is to find out where 1,2,3,4 contact points from the zoom pot connect to the A,B,C,D of the tajini connector to operate externally the zoom lense, one diagram for cannon, and one diagram for fuginon lenses.
If anyone does have this info please help.
Thanks in advance

According to the fax from CANNON I just received:

A=Zoom speed control
B=+V1
C=+V3
D=+V2
E=VTR Com(Grnd)
F=VTR Sw
G=Ret Com (Grnd)
H=Ret Sw
