The imaging apparatus includes an imaging element including an imaging surface on which light from a subject is incident, a first filter unit including an electronic first optical filter capable of changing a light transmittance, and a first drive mechanism that rotates the first filter unit about a first rotation center line between a first filtering position and a first retraction position. The first filtering position is a position where the first optical filter exists in front of the imaging surface of the imaging element and light before reaching the imaging surface passes through the first optical filter, and the first retraction position is a position where the first filter unit is out of the front of the imaging surface.
