Re: K6100 Focus

I think I need to figure out how to get into that part of the socket. The back part clips in and I have opened that, but still wasn't able to open the part in between the wire and the pin that contacts the tube pin.

If I remember correctly the actual socket for the focus pin mates with a contact in the plastic socket that connects to the focus wire. I had a 6100 that I had to hard wire that connection to get it to work. See if you can disassemble the connector and make sure the contacts are clean.
