K1 displays F in the LCD, but won't recognise a lens!

My K1 has just started displaying F in the LCD and won't recognize any lens I put on. Any suggestions would be greatly appreciated.

If this happens with every lens it might point to a larger defect, but have you tried cleaning the contacts on the camera mount?

Yes, I've cleaned the contacts, tried numerous lenses. Would a reset help?

Try it. Can't see how it could hurt, other than maybe having to re-enter some settings.

Looks like I'll have to send it in for repair ):

What lenses is it happening to?

Andykins67 · 08-15-2017, 09:58 PM

I've tried a Tamron 70-200 2.8, Sigma 105mm 2.8 and a Pentax 20-35mm F4.
