Optical format is a hypothetical measurement approximately 50% larger than the true diagonal size of a solid-state photo sensor.The use of the optical format means that a lens used with a particular size sensor will have approximately the same angle of view as if it were to be used with an equivalent-sized video camera tube (an "old-fashioned" TV camera).
