ABSTRACT:
A zoom camera having enhanced focusing stability during high magnification zooming under environments of high temperatures or low temperatures. When the zoom camera performs zoom-in operations in an environment of high or low temperatures, aperture control is added as the zoom magnification becomes higher and the temperature becomes higher or lower whereby the depth of field is made deeper to assure the presence of a range with good focusability.
