ABSTRACT:
In a camera according to the present invention, a driving source is driven using a zoom switch to adjust a focal distance value of a zoom optical system. In the meantime, a range finding unit measures a range to a subject. After zooming by means of the zoom switch is completed, an arithmetic logic unit serving as a focal distance determining unit and control computes the range finding value and the focal distance value to obtain a magnification for imaging a subject on film. A picture size selecting unit provides the arithmetic logic unit with a signal indicating that the picture frame is of a full size or a smaller size. Either of two-system processes each determining an imaging magnification is selected according to the signal. Thereby, an imaging magnification consistent with a picture size is specified automatically.
