This cute but weird distinction between the terms Depth of Field and Depth of Focus is amusing but terribly in error. As 1 hope you recognize, Depth of Field refers to the appearance of relative image sharpness in the objects in the scene toward which the lens is pointed. While there are certain generally accepted norms for describing this, there is a lot of room for definition and interpretation.
Contrarily, Depth of Focus refers to characteristics of the projected image inside the camera at the location of the film or digital sensor.
