I have a Sigma 70-300mm DL lens I used with my old N70 film camera. I recently upgraded to a D5000 and would like to use the lens with autofocus. Does anyone know if there is a converter to convert the focus signals from the camera to in-body focus drive?

Welcome to Nikonians! There is no such converter! You can use the lens but with Manual Focus only! If you want to AF with that lens you will have to upgrade to a D90 or higher body (current)! The older D50/D70/D70S/D100/D200 bodies also have AF motors built into the camera body. Good Luck and Enjoy your Nikons!

Anything is possible given enough time and money! The problem is any such adaptor would cost more than the price difference between a D3000 and a D90 as the demand for such a devise would be very low. It would also have to incorporate optical elements to correct for the additional distance between the camera body and the back of the lens. Similar to a TC. The TC-14E II sells for $350.00(gray) to $420.00(USA) without a motor or any mechanical linkage for "Screwdriver AF". Good Luck and Enjoy your Nikons!
