Digital camera with live view mode

A camera body to which an interchangeable lens is attachable detachable, having a movable mirror provided so as to enter or retract with respect to an optical path of an image pickup optical system for guiding a subject image to an optical viewfinder, the camera body comprising:

• an image pickup element that captures the subject image formed by the image pickup optical system to generate image data;
• a display portion that displays the image data generated by the image pickup element or image data obtained by subjecting the image data generated by the image pickup element to predetermined processing;
• a release portion that receives an instruction by halfway depression or full depression from a user;
• a photometric portion that measures an amount of light from a subject when the movable mirror is positioned in the optical path of the image pickup optical system;
• an attachment portion capable of attaching an illumination portion that illuminates the subject with light to the camera body;
• and
• a control portion having a live view mode controlling so that the image data generated by the image pickup element or the image data obtained by subjecting the image data generated by the image pickup element to predetermined processing is displayed on the display portion as a moving image in real time,
• wherein, when the digital camera is being operated in a live view mode, in a case where the amount of light from the subject is measured without allowing the illumination portion to flash light, the control portion controls so that the amount of light is obtained based on the image data generated by the image pickup element,
• while in a case where the release portion receives an instruction of starting capturing of an image and the amount of light from the subject is measured by allowing the illumination portion to flash light, the control portion controls so that the movable mirror enters the optical path of the image pickup optical system, the illumination portion flashes light, and measurement results of the photometric portion are obtained.
