Be patient with me.
I only recently began using digital, and have been thinking that a higher aperture will get me the longer depth of field. BUT, I did just realise that differences in depth of field in a traditional camera were caused by the physics of the light passing through different sized openings. On a digital camera, there is not actually a physical aperture?? just a difference in sensitivity? Does this mean that manual options on a digital camera cannot create these differences in the range of the focus? (or does the camera correct for this?)
scrap this one folks. sorry.. answered this. Still can't explain my struggle with focusing this thing.

Of course there is a physical aperture ;)
The difference you are talking aobut refers to the difference between using different apertures at different focal lengths (this is why it is cheaper to make a 17mm f/2.8 lens than a 600mm f/2.8 lens), but that is besides the point.
THe aperture in digicams works the same way as in all other cams (including the cams with fixed aperture, with the exception that you cannot change the aperture, obviously)
