2. Description of the Related Art

In recent years, the number of pixels of an image sensor used in an interchangeable lens type digital camera system is rapidly increasing. In order to record higher-definition images, it is necessary not only to increase the number of pixels in the imaging device, but also to improve the imaging performance of the imaging lens. Therefore, there is a demand for an imaging lens that suppresses the occurrence of aberrations. In addition, an increasing number of users are using interchangeable-lens digital camera systems to shoot not only still images but also moving images.
The

zoom lens 1 according to Example 1 is suitable for a so-called full-size (screen size: 36.0 mm×24.0 mm) imaging device. The zoom lens 1 according to Example 1 realizes an equisolid angle projection circular fisheye in the shortest focal length state, and an equidistant projection diagonal fisheye in the longest focal length state.
