Abstract
A camera of the kind permitting a shot either without any flash device or with a flash device is arranged to set a first camera-shake limit shutter speed to be used for a normal shot to be taken without using a flash device and a second camera-shake limit shutter speed for a flash shot to be taken by using a flash device and to select the first camera-shake limit shutter speed or the second camera-shake limit shutter speed according to whether the camera is in the normal shot mode or in the flash shot mode. With the camera arranged in this manner, the camera-shake limit shutter speed can be prevented from becoming an unnecessarily high speed when the camera is in the flash shot mode and can be set at adequate speeds both in the normal shot mode and in the flash shot mode. Therefore, a shot can be taken without causing the photographer any uncertainty in each of the two different modes.
