Abstract
A print format selection device for selecting one of different print formats to each picture frame of a filmstrip loaded in a camera or lens-fitted photo film unit, wherein an original field of view of a viewfinder corresponds to a picture frame defined by an exposure aperture of the camera. A rotatable view changing plate is provided to limit the original field of view in correspondence with the selected print format. The view changing plate is formed with two view windows of different aspect ratios from the original field of view. The centers of the view windows are on a circle which is coaxial with the rotational axis of the view changing plate and which extend across an optical axis of the viewfinder.
