Sorry, but this is simply wrong. As I posted yesterday, D-o-F depends, all
else being equal on image size. Two lenses, a 20mm & a 200mm set to the
same aperture and set at different distances to the target so the target is
the same size in the finder (and on film) will return the same D-o-F. The
angle of view may vary but D-o-F will not.
