Abstract
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.
Claims13
A zoom lens system comprising at least six lens groups, each of the at least six lens groups having power,
- an interval between each pair of lens groups that are adjacent to each other among the at least six lens groups changing 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 consisting of one or more bonded lenses.
An image capture device configured to transform an optical image of an object into an electrical image signal and output the electrical image signal thus transformed, the image capture device comprising:
- a zoom lens system configured to form the optical image of the object;
- and
- an image sensor configured to transform the optical image formed by the zoom lens system into the electrical image signal,
- the zoom lens system comprising at least six lens groups, each of the at least six lens groups having power,
- an interval between each pair of lens groups that are adjacent to each other among the at least six lens groups changing 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 consisting of one or more bonded lenses.
An interchangeable lens unit configured to be removably connected, via a mount, to a camera body, the camera body including:
- an image sensor configured to receive an optical image and transform the optical image into an electrical image signal;
- and the mount,
- the interchangeable lens unit comprising at least six lens groups, each of the at least six lens groups having power,
- an interval between each pair of lens groups that are adjacent to each other among the at least six lens groups changing while the interchangeable lens unit 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 consisting of one or more bonded lenses.
