Abstract
The invention relates to an electronic image pickup system whose depth dimension is extremely reduced, taking advantage of an optical system type that can overcome conditions imposed on the movement of a zooming movable lens group while high specifications and performance are kept. The electronic image pickup system comprises an optical path-bending zoom optical system comprising, in order from its object side, a-st lens group G-comprising a negative lens group and a reflecting optical element P for bending an optical path, a-nd lens group G-comprising one positive lens and a second lens group Ghaving positive refracting power. For zooming from the wide-angle end to the telephoto end, the second lens group Gmoves only toward the object side. The electronic image pickup system also comprises an electronic image pickup device I located on the image side of the zoom optical system.
