Get the circle of confusion diameter used in depth-of-field math for a sensor.
The accepted circle of confusion is a small fraction of the sensor diagonal, with stricter values for large prints viewed closely. Depth-of-field results only mean something when the blur tolerance (CoC) is set, so this value feeds every DoF estimate.
Circle of Confusion
CoC = sensor diagonal / 1500 (standard) or / 1730 (print)
CoC = sensor diagonal / 1500 (standard) or / 1730 (print) The accepted circle of confusion is a small fraction of the sensor diagonal, with stricter values for large prints viewed closely.
