Abstract
A digital still camera switches an image sensor between moving picture shooting and still picture shooting. The digital still camera includes a variable-magnification optical system having a plurality of lens groups of which four are movable. At least one of the movable lens groups travels different movement trails for magnification variation between during zooming in moving picture shooting and during zooming in still picture shooting.
