    Abstract: An inner focusing lens has sequentially from the object side, a first lens group having a positive refractive power, a second lens group having a negative refractive power, and a third lens group having a negative refractive power. The first lens group has negative meniscus lenses disposed farthest on the object side thereof. The second lens group is moved along the optical axis whereby focusing from a focus state for an object at infinity to a focus state for the minimum object distance is performed. The inner focusing lens satisfies predetermined conditions and thereby, realizes a compact inner focusing lens having high imaging performance at wide angles, suitable for compact cameras having a function of capturing video.

    Abstract: The infrared camera apparatus incorporates an infrared lens system that retains high resolution power and yet is successfully reduced in a required volume of infrared lens material that is hard to obtain and expensive, so as to attain a compact and cost-reduced infrared camera apparatus incorporating such an infrared lens system. The infrared lens system has at least a single Fresnel lens piece that has at least one of its opposite sides formed in a Fresnel surface. The Fresnel lens piece is made of a lens material of which transmissivity to light waves of one or more monowavelength(s) within an available wavelength range from 3000 nm to 14000 nm is 35% or higher when it takes a shape of 4-mm thickness uncoated parallel flat plate.

    Abstract: A zoom lens exhibits a reduction in size, increased magnification, a reduction in variation of angle of view during zooming, and an increased focusing speed, said zoom lens being suitable for an imaging apparatus using a solid-state imaging device such as an interchangeable lens, a digital still camera, a digital video camera, or the like. The zoom lens has, in the lens system, at least: a first negative lens group having negative refractive power; a second negative lens group disposed further towards the image side than the first negative lens group, and which has negative refractive power; and a lens group (A) disposed so as to be adjacent to the image side of the second negative lens group. In the zoom lens, focusing from an infinite distance to a near object is performed by moving only the second negative lens group towards the image side, and prescribed conditions are satisfied.
