    • 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.
    • 使用单个焦距的光学系统拍摄照片的伪焦距照相机。 打印的照片具有与通过使用包括多个具有不同焦距的多个摄影镜头的光学系统进行照片而获得的相似的特征。 指示与指定的伪焦距对应的图像形成区域的信息在拍摄照片并基于该信息进行打印时被记录在胶片上。 取景器光学系统包括用于显示根据与每个伪焦距对应的放大率而变化的图像形成区域的尺寸的液晶显示器。 在通过指定伪焦距来确定图像形成区域之后,通过在第一状态下按下释放按钮来打开第一开关。 结果,取景器光学系统的透镜被驱动,因此,与所确定的图像形成区域相对应的图像出现在取景器的整个区域中。 通过将释放按钮按压到第二阶段来实现曝光。
