FS: Pentax Auto extension tube set K boxed

FS: A Pentax Auto extension tube set K boxed in excellent condition with instructions, front cap and leather case in excellent condition.

Asking £35 to include signed for P&P.

Will accept BT or Paypal.

What info passes through the contacts from the lens to the body with these attached?

I'm pretty certain that no info passes between camera and lens with any of the Pentax made tubes, so every thing will need to be fully manual. They are however beautifully made

Thanks LennyBloke for answering that question as I had never used them.

Regards

Kevin
