ABSTRACT:
A pseudo focal length camera which takes a photograph using an optical system of a single focal length. A printed photograph has a feature similar to that obtained by taking a photograph using an optical system comprising a plurality of photographing lenses each having a different focal length. Information indicating an image forming area corresponding to a designated pseudo focal length is recorded on a film when a photograph is taken and a printing is carried out based on the information. The view finder optical system includes a liquid crystal display for displaying the size of an image forming area which changes according to a magnification corresponding to each pseudo focal length. After the image forming area is determined by designating a pseudo focal length, the first switch is turned on by the depression of the release button in the first state. As a result, the lens of the view finder optical system is driven and consequently, the image corresponding to the determined image forming area appears in the whole area of the view finder. An exposure is effected by the depression of the release button to the second stage.
