In a zoom camera disclosed, a memory of an auto-zooming program lines is provided in which a relation between the object distance and the image mangification added with an element of the depth of field is set in a predetermined manner according to each kind of photographing mode, and such a focal length of a focusing lens is computed that the image mangification is set to be a predetermined value based on the object distance and a program line of a photographing mode selected by a user, whereby the focusing lens is driven so as to obtain the focal length. Consequently, auto-zoom photographing at a depth of field and an image magnification suitable for each kind of photographing mode can be achieved. Further, a memory of program lines set according to the vertical and horizontal camera attitudes in photographing is provided, and the image mangification can be changed over according to each camera attitude.
