Since the following macro works:

http://www.wozzeck.net/images/DoF.html

it seems that aperture has the "right" value... I mean that f-stops are
actually focal-length-divided-by... values. Eg. your nice 300mm f/2.8
has an "aperture" of 107 mm. The problem is to determine the "focal
length" of your camera, which is certainly not the one you get in 24x36
mm. See the macro page and source for more details.
