Conventionally, imaging devices using solid-state imaging elements such as digital still cameras and digital video cameras have been widely used. There are various types of such imaging devices, such as digital still cameras, digital video cameras, broadcast cameras/film cameras, surveillance cameras, and vehicle-mounted cameras. As the light-receiving elements that make up the solid-state imaging elements become more highly integrated, the functionality of each imaging device has increased while the device has become smaller. There is a demand for even higher performance and smaller size in the imaging optical system of the imaging device. - [0003]
As an imaging optical system used in an imaging device, there is a high demand for a zoom lens that can change the focal length according to the subject. A zoom lens is required to have a large variable magnification ratio while suppressing an increase in size. In addition, a zoom lens in which various aberrations are well corrected throughout the entire focus range is desired, and the floating method in which multiple lens groups are moved during focusing is increasingly being adopted. - [0008]
It is therefore an object of the present invention to provide a zoom lens and an image pickup apparatus which are compact and have high optical performance over the entire focus range while realizing a high zoom ratio.
Example 1
- Focal length: 51.5012-192.9993
- F value: 2.9100
- Half angle of view: 22.9584-6.1335
