Good grief, Hemming. The DOF is HIGHLY dependant on the COC. The COC significantly modifies the DOF for the same focal length, aperture, and distance. Example: 50mm, f2.8, 1M subject distance: COC of .033 gives a DOF of 0.07M COC of .06 gives a DOF of .128M Clearly, the COC highly modifies the DOF.
