摘要
A fixed focal length imaging optical system includes first lens group (G1) having positive power, second lens group (G2) having positive power, and third lens group (G3) having negative power in order from an object side toward an image side. Upon focusing, second lens group (G2) moves along an optical axis, and first lens group (G1) and third lens group (G3) do not move. The present disclosure provides the fixed focal length imaging optical system capable of favorably correcting various aberrations such as spherical aberration, astigmatism, and distortion, and an imaging device and a camera system each of which includes the fixed focal length imaging optical system.
