Abstract
A camera having a zoom lens. The camera includes a shutter, an aperture and program exposure mode control. The program exposure control includes one or more reference program characteristics representing combinations of shutter speed and aperture corresponding to one or more of a portrait mode, a landscape mode and a close up mode. Each reference program characteristics define a predetermined aperture in a first range from a low shutter speed to a hand-induced vibration limit and defines a different aperture in a second range beyond the hand-induced vibration limit. One of the reference program characteristics is selected, wherein the hand-induced vibration limit is defined in accordance with a focal length of said zoom lens.
