I am looking for extension tubes to use with my F*300 f4,5 and my future K10D, but over at Bojidar Dimitrov's site I found that no extension tubes were done by pentax with A contacts. As my use would be for butterflies and other insects, I need to preserve the fully automation of the camera (minus focus).

I have checked Kenko website, but the extension tubes there seems to be not available in pentax mount. Does anybody knows if there exists extension tubes from any manifacturer with A contacts?

I got a set of kenko auto extension tubes from B&H. Name on Barcode is
EX TUBE PAF. They work well and send lens data to the camera, manual focus.

B&H list the set as out of stock, and I am fearing it has to do with the fact that they are not listed anymore on the Kenko site.

Has anyone heard of another brand, hopefully?

Vivitar AT-23 should work. I haven't bought it, but I'm considering. See this thread at dpreview

B&H has them as well for 90$. They seem to be in stock.
