  • Kind Code: A1 A compact, lightweight, high-performance optical system and imaging apparatus suitable for a compact imaging system, and having an open Fno greater than 2.0 are provided.
  • 2. Description of the Related Art
    Conventionally, photographing apparatuses using solid-state image sensors, such as digital still cameras and digital video cameras, have been widely used. As the number of pixels of solid-state imaging devices used in these imaging devices increases, optical systems are required to have high resolution performance while maintaining compactness and light weight.
  • [0003]
    Further, as the size of the solid-state imaging device is increased, a large blur is required. Therefore, the optical system requires a large-aperture lens with a shallow depth of field and a brighter aperture Fno than 2.0.
