    摘要: The invention relates to an expensive zoom lens that has a zoom ratio of as high as about 5 and high optical performance and is very thin in its depth direction. With the invention, the optical path of the optical system is easily bendable by means of reflecting optical members. The zoom lens comprises a plurality of lens groups G1 to G5, and has a lens group F (G1) located nearest to the object side thereof. The first optical path bending is carried out by the first reflecting optical member PR located in the lens group F, and the second optical path bending is carried out by the second reflecting optical member RM located on an image side of the zoom lens with respect to the lens group F in a direction different from the first optical path bending direction. The lens group F remains substantially fixed with respect to an image plane I during zooming.

    摘要: The invention relates to a less costly zoom lens that can offer a sensible tradeoff between size reductions and high zoom ratios with a well-kept image quality, and that lends itself to an electronic imaging device such as a CCD or CMOS. The zoom lens comprises a positive first lens group G1, a negative second lens group G2, a positive third lens group G3 and a positive fourth lens group G4, wherein zooming is implemented by changing the space between adjacent lens groups. The first lens group G1 comprises one positive lens, the second lens group G2 comprises two lenses, and the fourth lens group G4 comprises one positive lens. The zoom lens satisfies condition (1) needed for making sure an ideal situation for the zoom ratio and low costs and condition (2) needed for the first lens group to comprise a minimum one lens and to hold back chromatic aberration of magnification as much as possible.

    摘要: A zoom lens comprises, in order from its object side, a front lens group having negative refracting power at a wide-angle end and a rear lens group having positive refracting power at the wide-angle end. The front lens group comprises, in order from the object side, a first lens group of positive refracting power and a second lens group of negative refracting power, and the rear lens group comprises, in order from the object side, a third lens group of positive refracting power and a fourth lens group of positive refracting power. There is an aperture stop interposed between the lens surface located in, and nearest to the object side of, the second lens group and the lens surface located in, and nearest to the image size of, the third lens group. Upon zooming from the wide-angle end to the telephoto end, the spacing between the first lens group and the second lens group grows wide, the spacing between the second lens group and the third lens group becomes narrow, the spacing between the third lens group and the fourth lens group changes, and an F-number grows greatest when the aperture stop is open in the course of zooming from the wide-angle end to the telephoto end.
