A camera includes a finder for enabling an image which is shot on a film to be monitor-displayed by branching a portion of a light beam (image) imaged by a picture-taking lens system, by an up/down movable pellicle mirror comprised of a half mirror, to let the image be received on a image pick-up device. In this camera, a pupil-dividing LCD is arranged in front of the image pick-up device to impart a phase difference to the light beam imaged by the picture-taking lens system to obtain corresponding image data. By doing so, phase difference AF control is carried out. The image pick-up device has both the function of monitoring a pick-up image and the function of detecting a just-in-focus state.
