I use Vivitar tubes, which have both the electronic and mechanical
couplings.

Subject: Extension tubes on the *istD
I have a set of Vivitar tubes in a plain K mount. Those will effectively
make an FA lens into a K mount, AFAICS, since they don't have the contacts
to let the body know it's got an A-series lens on it.
Pentax don't seem to make extension tubes any more (although Pentax
USA sell a wider range of lenses and accessories than Pentax UK,
neither lists extension tubes). Does anyone sell A-compatible tubes?
