Abstract
An optical system includes, in order from an object side to an image side, a front group, an aperture stop, and a rear group that has positive refractive power as a whole. The front group includes a first lens having negative refractive power disposed closest to an object. The rear group includes a final lens having positive refractive power disposed closest to an image plane. The optical system includes four or more lenses disposed between the first lens and the final lens. A lens surface near an optical axis of the final lens has a meniscus shape with a convex surface on the object side. Predetermined inequalities are satisfied.
