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? -- PDML means I get more e-mail than spam!
