(Once again) ... cropping occurs due to the sensor's physical size, not due to the (DA or FA) lens image circle.

Non-DA lenses have a larger image circle but the APS-C sensor only captures the middle part; the larger part on the outside is good for use but doesn't get used. It bears no relation to cropping.
