The object of the present invention is to provide an imaging apparatus capable of preventing the degradation of image quality associated with a temperature rise in an image pickup device despite that an electronic viewfinder is usable. An imaging apparatus including an image pickup device for capturing a subject image to acquire it as image data and capable of viewing a subject by selecting either of a first finder mode for optical viewing of the subject image and a second finder mode for displaying the image data on a display unit to allow viewing of the image data, the imaging apparatus comprises: a temperature detection circuit for measuring the temperature of the image pickup device; a finder mode switching instruction part for switching between the first finder mode and the second finder mode; and a controller for inhibiting switching from the first finder mode to the second finder mode performed by the finder mode switching instruction part when the temperature exceeds a first threshold.
