Abstract: An imaging lens is constituted essentially by, in order from the object side to the image side, a negative first lens group, a positive second lens group, a stop, and a positive third lens group. The first lens group is constituted essentially by four or fewer lenses, has a positive lens and a negative meniscus lens provided adjacent to each other in this order from the most object side, and further has a negative lens at the most image side. The second lens group is constituted essentially by one single lens. The third lens group is constituted essentially by five or fewer lenses, and has four lenses having refractive powers of different signs adjacent to each other provided in order as lenses most toward the image side. Predetermined conditional formulae are satisfied.

Abstract: Provided are a lens device, an imaging apparatus, and a filter unit capable of suppressing occurrence of ghosts and flares. The lens device includes a first optical filter and a second optical filter in order from an object side in an optical path. The first optical filter is composed of an optical filter (for example, a band-pass filter) that has a light transmission band in a specific wavelength region. The second optical filter is composed of an optical filter (band-stop filter) that has a light absorption band in a wavelength region which is different from the light transmission band of the first optical filter.

Abstract: The variable magnification optical system consists of, in order from an object side to an image side, a first lens group that has a positive refractive power, a plurality of lens groups, and a final lens group that has a positive refractive power. During changing magnification, a spacing between the first lens group and the lens group closest to the object side among the plurality of lens groups changes, all spacings between adjacent lens groups in the plurality of lens groups change, and a spacing between the lens group closest to the image side and the final lens group among the plurality of lens groups changes.

Abstract: The zoom lens consists of, in order from an object side: a positive first lens group that does not move during zooming; a middle group that consists of two or more movable lens groups moving during zooming; and a subsequent group that has a lens group including a stop at a position closest to the object side. The middle group has at least two negative movable lens groups. The subsequent group includes at least one positive LA lens that satisfies predetermined conditional expressions relating to the refractive index, the Abbe number, and the partial dispersion ratio.

Abstract: The imaging lens includes, in order from the object side, a first lens group that remains stationary during focusing; a diaphragm; and a positive second lens group that moves to the object side during focusing from a long range to a close range. The second lens group includes a positive Z lens that is formed continuously in order from a most image side, a negative Y lens that has an absolute value of a radius of curvature of an object side surface smaller than an absolute value of a radius of curvature of an image side surface, a positive X lens, and a negative W lens that has an absolute value of a radius of curvature of an image side surface smaller than that of an object side surface. The imaging lens satisfies a conditional expression about of the radii of curvature of the X lens and the W lens.
