Try a search on PN or Google for "depth of field" (use the quotations) and you should find more than you'd care to know about getting things at different distances in focus. It turns out the small sensor on your Kodak created conditions for very wide depth-of-field (aka DOF), and the larger sensor on your k10d will require you to pay a bit more attention. The good news is this is a proverbial "good thing".
A couple of tutorials I found quickly: http://www.cambridgeincolour.com/tutorials/depth-of-field.htm http://en.wikipedia.org/wiki/Depth_of_field
