An imaging optical system consists of: a first lens group having positive power; a second lens group having negative power; and a third lens group having positive power. The first lens group and the third lens group are fixed with respect to an image plane, with the second lens group moving along an optical axis, while the imaging optical system is focusing to make a transition from an infinity in-focus state toward a close-object in-focus state. The first lens group consists of: a sub-lens group GA; an aperture stop; and a sub-lens group GB. The sub-lens group GA includes: a lens LAhaving negative power; a lens LAhaving negative power; and a lens LAhaving negative power.

Imaging optical system, image capture device, and camera system

An imaging apparatus includes: an imager configured to capture a subject image to generate image data; a controller that records an image file based on the image data on the recording medium; and an operation interface that inputs a user operation for selecting a file system from first and second file systems different from each other, the file system managing the image file in the recording medium, wherein in accordance with the user operation input in the operation interface, the controller switches a folder for storing the image file between a first folder corresponding to the first file system and a second folder corresponding to the second file system in the recording medium.

Imaging apparatus

A zoom lens system includes at least six lens groups, each of which has power. An interval between each pair of lens groups that are adjacent to each other among the at least six lens groups changes while the zoom lens system is zooming. Each of three lens groups, which are respectively located closest, second closest, and third closest to an image plane, out of the at least six lens groups consists of one or more bonded lenses.
