Definitions
- the present invention relates to a zoom lens system, an imaging device, and a camera.
- the present invention not only has a high resolution, but also has a short optical total length (lens total length), a large zoom ratio of about 5 times, and a wide angle at a wide angle of about 70 °.
- the present invention relates to a zoom lens system that can be sufficiently adapted for photographing, an imaging device including the zoom lens system, and a thin and extremely compact camera including the imaging device.
- a first lens group having a negative power, a second lens group having a positive power, and a positive lens are sequentially arranged in order from the object side to the image side.
- Zoom with a short optical total length (lens total length: distance from the apex of the lens surface closest to the object side to the image plane in the entire lens system) in a negative lead type three-group configuration in which a third lens group having the same power is arranged
- Various lens systems have been proposed.

Each lens group is moved so as to reduce the distance between the second and third lens groups, and zooming is performed.
- the first lens group is composed of two negative and positive lenses
- the second lens group is composed of two independent positive and negative lenses.
- the third lens group consists of one positive lens, and the radius of curvature of the object side surface of the negative lens included in the second lens group satisfies the specific relationship between the focal length at the wide-angle end of the entire system.
- a zoom lens is disclosed.
- the zoom lens disclosed in Japanese Patent No. 3513369 has a reduced optical total length and has high optical performance over the entire zoom range.

- the focal length at the wide-angle end, the axial distance between the first and second lens groups and the focal distance of the first lens group, the axial distance between the first and second lens groups and the focal distance of the second lens group are specified.
- a zoom lens that satisfies this relationship and has a zoom ratio in a specific range is disclosed.
- the zoom lens disclosed in Japanese Patent Application Laid-Open No. 2006-301154 has a large angle of view at the wide angle end and a relatively large zoom ratio.
- Japanese Patent Application Laid-Open No. 2006-065034 has three negative and positive lens groups in order from the object side to the image side, and the distance between the lens groups changes at the time of zooming.
