Abstract: A lens system, an interchangeable lens apparatus, and a camera system each include a front group including a first focus lens group that moves with respect to an image surface in focusing from an infinity in-focus condition to a close-object in-focus condition; a rear group including a second focus lens group that moves with respect to the image surface in focusing, the front group and the rear group being located in order from an object side to an image side; a fixed lens group including at least one positive power lens element, the fixed lens group being located between the front group and the rear group and fixed with respect to the image surface in focusing; and an aperture diaphragm. The positive power lens in the fixed lens group satisfies dPgF>0.015 (dPgF is an anomalous dispersibility in a g-line and an F-line of the lens element).

Abstract: A zoom lens system includes: a first lens group having positive power; a second lens group having negative power; a third lens group having positive power; a fourth lens group having negative power; and a fifth lens group having positive power. The first lens group is made up of a single lens. The second lens group is made up of four lenses. While the zoom lens system is zooming from a wide-angle end toward a telephoto end during a shooting session, the fifth lens group does not move but the first to fourth lens groups move to change intervals between the lens groups.

Abstract: An oblique viewing endoscope has an aperture through which some rays out of rays reflected from an object in an oblique viewing direction pass, an imaging element that captures an image, based on image forming of the rays passing through the aperture, and a lens that is disposed between the aperture and the imaging element, and that has a lens surface on which the image is formed by causing some rays in at least a visual field center out of the rays passing through the aperture in the oblique viewing direction to be substantially vertically incident on a center of the imaging element.
