Re: K6100 Focus

Did you check the integrity of the focus wire connection under the rubber boot where it connects to the focus block?

I've seen many of these where the wire was barely holding on with just a few strands of wire.

Just a thought.

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.
