2. Description of the Related Art
In recent years, image pickup devices such as digital cameras have become larger in size and higher in image quality. high performance is also required. On the other hand, as the use of mirrorless cameras and the like advances toward short flange focal distances, miniaturization of optical systems is also required. In addition, in the case of digital camera systems with interchangeable lenses, the number of cases where not only still images but also movies are shot is increasing. etc. are also required. - [0004]
As described above, imaging lenses are required to have high performance and to be compact. Also, when shooting moving images, it is required to suppress fluctuations in the angle of view during focusing. - [0005]
It is desirable to provide an imaging lens that is compact and has a large aperture, yet has high optical performance and that suppresses variation in the angle of view during focusing, and an imaging apparatus equipped with such an imaging lens.
