An imaging apparatus comprises: an imaging unit having an imaging optical system and an imaging device; a measuring unit that measures, for each of a plurality of regions on a specimen, an optical aberration or a physical quantity causing the aberration before the imaging of the specimen is performed; a plurality of optical elements that are inserted in an optical path of the imaging optical system for correcting the aberration and that differ in correction amount; and a control unit that selects an optical element from among the optical elements on the basis of a measurement result of the measuring unit, and inserts the selected optical element into the optical path of the imaging optical system before the imaging of the specimen. The imaging optical system is configured to be capable of forming simultaneously images of the plurality of regions on the imaging device.
