摘要： The object of the invention is to reduce the thickness of electronic image pickup equipment as much as possible, using a zooming mode having stable, high image-formation capabilities from an object at infinity to a near-by object. The electronic image pickup equipment comprises a zoom lens system comprising a negative, first lens group G1, a positive, second lens group G2 and a positive, third lens group G3. For zooming from the wide-angle end to the telephoto end of the zoom lens system upon focused on an object at infinity, the separation between G2 and G3 becomes wise. By moving G3 toward the object side of the system, the system can be focused on a nearer-by object. In the zoom lens system, the second lens group G2 comprises one positive lens 2a, one negative lens 2b and a lens subgroup 2c comprising at least one lens, and the third lens group G3 comprises one positive lens. The zoom lens system satisfies conditions with respect to the optical axis distance from the image-side surface of the positive lens 2a to the image-side surface of the negative lens 2b and the focal length ratio in air between the positive lens 2a and the lens subgroup 2c.

摘要： The invention relates to an imaging system in which, while high image quality is maintained with the influence of diffraction minimized, the quantity of light is controlled, and which enables the length of the zoom lens to be cut down. The imaging system comprises a zoom lens comprising a plurality of lens groups G1 and G2 wherein the spacing between individual lens groups is varied to vary a focal length and an aperture stop located in an optical path for limiting at least an axial light beam diameter, and an electronic image pickup device I located on the image side of the zoom lens. The aperture stop has a fixed shape, and a filter S2 for performing light quantity control by varying transmittance is located on an optical axis of a space located at a position different from that of a space in which the aperture stop is located.

摘要： 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 1-1st lens group G1-1 comprising a negative lens group and a reflecting optical element P for bending an optical path, a 1-2nd lens group G1-2 comprising one positive lens and a second lens group G2 having positive refracting power. For zooming from the wide-angle end to the telephoto end, the second lens group G2 moves 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.
