>A good rule of thumb with current consumer-grade CCD sizes is that digital DOFs are roughly equivalent to DOF on a 35 mm camera with an aperture 5 stops smaller. Thus a digital aperture of f/4 gives the same DOF as a 35 mm f/22 <
I've heard this before and the common wisdom is certainly that DOF is BETTER with digital. In fact, I read one article saying the author had some concern about how to reproduce the typical portrait shot where the face is in focus and background blurred, because DOF was too good. So, I'm not contesting your point. But I have to say I have had some trouble managing depth of field with my digital equipment. I think I need more digital experience.
