Abstract: The zoom lens includes, in order from the object side, a first lens group that has a positive refractive power, a second lens group that has a negative refractive power, a third lens group that has a positive refractive power, a fourth lens group that has a positive refractive power and has a stop disposed to be closest to the object side. During zooming, the second lens group and the third lens group move, and the other lens groups remain stationary. The first lens group consists of, in order from the object side, two groups of cemented lenses in which a negative meniscus lens and a positive lens are cemented, and a cemented lens in which a positive lens and a negative lens are cemented. During focusing, only the cemented lens closest to the image side in the first lens group moves.

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: A lens control device includes a processor that performs a control of generating image data for each of first wavelength range light and second wavelength range light by an image sensor, in which the processor estimates a first focus position of a focus lens for the first wavelength range light based on a first focus evaluation value determined in accordance with the image data of the first wavelength range light, estimates a second focus position of the focus lens for the first wavelength range light based on a second focus evaluation value determined in accordance with the image data of the second wavelength range light, and performs a control of moving the focus lens along an optical axis based on the first focus position in a case in which a comparison result obtained by comparing the first focus position with the second focus position satisfies a predetermined condition.

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.

Abstract: Provided are an imaging controller, an operation method and program of the imaging controller, and a camera capable of presenting a radiation image of a subject to a user in an easy-to-understand manner. An image sensor driving control unit causes an image sensor to image a visible ray to acquire a first image including a reflected image of a subject. The image sensor driving control unit causes the image sensor to image an infrared ray to acquire a second image including the reflected image and a radiation image of the subject. A zoom lens driving control unit moves a zoom lens along an optical axis to correct a difference in angle of view between the first image and the second image. Image processing units output difference images between the first image and the second image acquired in a state in which the difference in angle of view is corrected.
