Can anyone tell me more about this focus system? Is it simply a wired focus controller? I don't yet have the correct 3-pin Fischer cable to test it. It uses one 9-v battery.
I'll likely sell it, along with other incidental items that we picked up in some auction lots, but I wanted to know what it was first.
