Abstract: A zoom lens system includes at least six lens groups, each of which has power. An interval between each pair of lens groups that are adjacent to each other among the at least six lens groups changes while the zoom lens system is zooming. Each of three lens groups, which are respectively located closest, second closest, and third closest to an image plane, out of the at least six lens groups consists of one or more bonded lenses.

Abstract: A lens system includes a plurality of lens elements arranged from an object side to an image plane side, and a diaphragm arranged between the plurality of lens elements. The plurality of lens elements include a plurality of freeform lenses each having a freeform surface that is asymmetrical with respect to a first direction and a second direction which cross with each other. At least one freeform lens is placed on the image plane side of the diaphragm. With a lens thickness T1 in the first direction at a maximum height of an axial ray and a lens thickness T2 in the second direction at the maximum height of the axial ray, at least one freeform lens satisfying 0.3

Abstract: An imaging device includes a free-form lens having a shape in which (i) in a long-side direction of an imaging element, a resolution that changes along an optical axis long-side resolution curve, and the resolution that changes along a distant point long-side resolution curve in a position away from an optical axis, (ii) in a short-side direction, the resolution that changes along an optical axis short-side resolution curve, and the resolution that changes along a distant point short-side resolution curve in the position away from the optical axis, (iii) the distant point long-side resolution curve follows a shape of the optical axis long-side resolution curve, and has a higher resolution than the optical axis long-side resolution curve, and (iv) the distant point short-side resolution curve follows a shape of the optical axis short-side resolution curve, and has a higher resolution than the optical axis short-side resolution curve.
