Re: K6100 Focus

Late to the party here, but I third that sentiment.. The wire contact can break off in the tube socket, had to hard wire it before too.. Disassemble that thing and triple check.

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.
