I found an extremely cheap Canon J15x9.5B 2/3" zoom and was wondering if it may be useful on a standard 16mm camera. Before I gave it to a proffesional tech I was going to bench mount it in front of my Eclair ACL and take a look. To do this I need to know where the reference plane is on the lense mount. Like where is the flange focal distance measured from on the mount. It's a B4. I'm not familiar with the electronic cameras and the B4 mount on the cameras, so not sure where to measure from on the mount on the lense. The main flange is stepped to a smaller one to the rear.
Any help on that?

Cheers
Gregg
