ABSTRACT:
A camera is so structured that trimming photographing in which the F-number of the photographing optical system does not change is preferentially selected for the zoom-up photographing of a dark object field, so that the shutter time does not extend unnecessarily and the risk of hand-vibrated photographing is reduced.
