Zusammenfassung:	Problems, such as unevenness of exposure, caused by the difference in speed between a first curtain and a second curtain and a positional shift between the curtains (the occurrence of an edge darkening phenomenon) can be prevented. In addition, power consumption is reduced. When the shutter speed is set to be low by exposure control means, the exposure start operation is performed using an electronic focal plane shutter function of an image sensor (an electronic focal plane shutter is used for the first curtain), and an exposure end operation is performed by a mechanical focal plane shutter. In contrast, when the shutter speed is set to be high by the exposure control means, the exposure start operation and the exposure end operation are performed using the mechanical focal plane shutter (the mechanical focal plane shutter is used for the first curtain).
