A digital camera comprises a camera body and an image sensing unit. The image sensing unit is provided with a taking lens and an image sensing device for taking images and with an optical viewfinder. The camera body is provided with a controller for controlling the camera, signal processing circuits for processing signals from the image sensing device, a display device for displaying images taken and an interface for recording images taken onto a memory card. The display device serves as a viewfinder. In taking a image, the controller performs an AF control of the taking lens. When power supply to the camera is started, and when the display device is activated, the controller sets the taking lens at a predetermined focus position where in-focus condition is obtained for distant to close-range views, so that blurred images are not displayed on the display device.
