Summary:PROBLEM TO BE SOLVED: To provide a single-lens reflex camera capable of facilitating operation required when mirror-up photographing. SOLUTION: When a lock-releasing button 304 is depressed and the surface 310F of a 1st lever 310 is made to move to a position P3 where it is pressed the most, mirror-up operation for holding a mirror in a flipped up state by rocking an operation knob 302 from a position shown by a solid line to a position shown by an alternate long and two short dashes line is realized. When the button 304 is depressed and the surface 310F of the 1st lever 310 is moved from a position P1 to a position P2, a mirror-up switch 316 is turned on. Based on the turning-on of the switch 316, AE arithmetic operation for arithmetically calculating the exposure value is performed, and the exposure value is temporarily stored in a RAM. With the depressing operation of a release button, exposure control is performed based on the exposure value stored temporarily in the RAM and a shutter is released.
