Abstract: A zoom lens consists of a positive first lens group, a negative second lens group moved from the object side to the image plane side during zooming from the wide angle end to the telephoto end, a positive third lens group moved during zooming, and a positive fourth lens group, in order from the object side. The second and third lens groups each pass through a point where the imaging magnification of each corresponding lens group is −1× at the same time during zooming from the wide angle end to the telephoto end. The fourth lens group includes, on the most object side, a vibration-proof lens group, composed of a negative lens, a positive meniscus lens with a convex surface on the object side, and a negative lens, in order from the object side, and either one of the negative lenses satisfies predetermined conditional expressions.

Abstract: The zoom lens consists of, in order from an object side to an image side, a front group, an intermediate group, and a rear group. The front group consists of two or fewer lens groups that have positive refractive powers. A lens group closest to the object side in the front group remains stationary with respect to an image plane during zooming. The intermediate group consists of two or fewer lens groups that have negative refractive powers. The rear group consists of a plurality of lens groups. A lens group closest to the object side in the rear group has a positive refractive power, and a lens group closest to the image side in the rear group remains stationary with respect to the image plane during zooming. During zooming, all the spacings of adjacent lens groups change. The zoom lens satisfies predetermined conditional expressions.

Abstract: A zoom lens essentially consists of positive first lens group, negative second lens group, negative third lens group, negative fourth lens group, and positive fifth lens group in this order from an object side. First and fifth lens groups are fixed with respect to an image plane, and second through fourth lens groups move in such a manner that a distance from each other changes when magnification is changed from a wide angle end to a telephoto end. First lens group essentially consists of 11th lens group having negative refractive power, 12th lens group having positive refractive power, and 13th lens group having positive refractive power in this order from the object side. 11th and 13th lens groups are fixed with respect to the image plane and 12th lens group moves during focusing.

Abstract: The zoom lens substantially consists of a positive first lens group fixed while changing magnification, a negative second lens group which moves from the object side to the image side while changing magnification, a positive third lens group which moves while changing magnification, and a positive fourth lens group which moves from the image side to the object side while changing magnification, and a positive fifth lens group fixed while changing magnification in this order from the object side. A floating system in which the third lens group and the fourth lens group move relative to each other while changing magnification is adopted. The image formation magnification rates of the combined lens group formed by the third lens group and the fourth lens group together and the second lens group simultaneously pass −1× point while changing magnification from the wide angle end to the telephoto end.

Abstract: An imaging apparatus includes an imaging optical system that has a light transmission characteristic of transmitting near-infrared light in a near-infrared light wavelength range including 1550 nm and transmitting visible light in a visible light wavelength range, a switchable filter that selectively transmits the near-infrared light and the visible light, an imaging sensor that has sensitivity to heat radiation from a subject and the visible light, and outputs an imaging signal by selectively transmitting the near-infrared light and the visible light, and an image processor that generates near-infrared image data based on the imaging signal output by imaging the near-infrared light with the imaging sensor, generates visible image data based on the imaging signal output by imaging the visible light with the imaging sensor, and generates image data representing a heat radiation image by subtracting the visible image data from the near-infrared image data.

Abstract: Provided is a lens device provided in an imaging apparatus body including an image sensor, the lens device including a processor, a a memory coupled to or integrated with the processor, a lens that includes a movement lens and that images incident light on the image sensor, and a drive mechanism that moves the movement lens by applying power to the movement lens along a coordinate plane intersecting an optical axis of the lens. The processor is configured to perform, with respect to the drive mechanism, control of changing a movement amount of the movement lens based on a wavelength range of the light transmitted through the movement lens.
