ABSTRACT:
A digital single-lens reflex camera comprises: an optical viewfinder; a retractable movable mirror for guiding subject images to the optical viewfinder; an image display device, serving as an electronic viewfinder, for displaying a subject image captured by an image-capturing device with the movable mirror retracted from the optical path; and a control device for starting image data acquisition with the image-capturing device after elapsing of a predetermined time, taking into consideration the amount of time necessary for the movable mirror to be retracted from the optical path and maximum diaphragm driving time of a diaphragm driving unit, following the user making a releasing operation while displaying a moving image on the image display device. This realizes a digital single-lens reflex camera which allows settings wherein the shutter release time lag is constantly the same, regardless of whether the optical viewfinder or the electronic viewfinder is used.
