摘要： The invention relates to a zoom lens and an imaging apparatus incorporating the same. The zoom lenses comprises, in order from its object side, 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. Zooming is implemented by changing the spacing between the respective lens groups. Upon received in a lens mount, the third lens group is shifted and positioned while its optical axis is tilted at an angle of ±45° with those of other lens groups or placed substantially horizontal. At least one of lenses in the second lens group G2 or the fourth lens group G4 is configured such that a portion of that lens proximate to the third lens group being received in the lens mount is cut away. The following condition (1) is satisfied: 0.3

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.

摘要： The invention relates to a four- or five-group zoom lens that ensures wide-angle performance, high zoom ratios and high quality with a more reduced number of lenses than ever before. The zoom lens comprises, in order from its object side, a first lens group G1 having positive power, a second lens group G2 having negative power, a third lens group G3 having positive power, a fourth lens group G4 having negative power and a fifth lens group G5 having positive power. The fourth lens group G4 comprises one lens. For zooming, all the spacings between the respective lens groups vary and the first lens group G1 moves in such a way as to arrive at the object side at the telephoto end position rather than at the wide-angle end position.

摘要： An image pickup apparatus includes: a zoom lens; an image pickup element having an image pickup surface which receives an image which has been formed by the zoom lens, and converts to an electric signal; a shading correction parameter storage section which stores a shading correction parameter which differs at a front-surface side and a rear-surface side with respect to a center of an image, which is for correcting asymmetric shading at the front-surface side and the rear-surface side of the zoom lens; and a shading correction section which carries out correction operation of an image which has been picked up by the image pickup element, based on the shading correction parameter of the shading correction parameter storage section. When an object having a uniform brightness is captured, at any state from the wide angle end to the telephoto end, the zoom lens satisfies conditional expression (A).

摘要： In 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, the optical path of the optical system is easily bendable by reflecting optical members. The zoom lens includes 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.
