May be you have a very good eye/brain for judging distance, by
calculation a 40mm lens at F2.8 and 5 feet distance the DOF is +/- 5
inches, I honest say I can't do this. Even yes, the center of focus
may not be right and I can't keep a control on the in-focus area. That
mean if I get accurate focus on the eye of the object and I expect the
hair at a few inches after the eye can be inside the DOF range. BTW
DOF only means you can get 30lp/mm resolution in a 35mm system, my XA
can resolve much more than that even wide open.
