Not sure if we're talking the same thing. With DOF and HFD, they are kind of opposites really. DOF is variable by changing the aperture, HFD is fixed for a given focal length / aperture.

I suppose HFD can be thought of as maximum DOF but HFD rules only apply when focused to infinity. They do not work at all if focused at anything else - or at least that's how I understood it.

"the hyperfocal distance is the distance beyond which all objects are acceptably sharp, for a lens focused at infinity."

p.s. all my Nikon lenses (and Sigmas for that matter) have the infinity mark.
