An image capturing apparatus includes a shutter spring which urges a shutter drive member for driving shutter blades, a shutter charge unit which is used to charge the shutter spring, and is switched between a fixed state in which a charge operation of the shutter spring is complete, and the shutter drive member is fixed and a released state, and a drive unit which drives the shutter charge unit. When a second determination unit determines that a switching ready state of a mirror from a mirror-down state to a mirror-up state is set when a first determination unit determines that a charge operation of the shutter spring is complete, the drive unit is controlled to drive the shutter charge unit to the released state without latch the shutter charge unit in the fixed state after the charge operation of the shutter spring is complete.
