  • Publication number: 20250338016
    Abstract: An imaging apparatus includes: an imaging element having an imaging surface on which light from a subject is incident; a switcher switching a state of the light between first and second states, the state being changed by an optical filter; a display device; and a processor controlling the imaging element, the switcher, and the display device. The processor determines whether the state is the first or second state. In response to determining that the state is the first state, the processor controls the display device to display first information indicative of a first range of a shooting distance that is capable of being set in the first state. In response to determining that the state is the second state, the processor controls the display device to display second information indicative of a second range of the shooting distance that is capable of being set in the second state.
