Original Abstract Submitted
An optical system includes, in order from an object side to an image side, a first lens unit having negative refractive power, an aperture stop, and a second lens unit having positive refractive power. The first lens unit includes a first lens having negative refractive power disposed closest to an object. The first lens has a meniscus shape that is convex to the object side. A predetermined condition is satisfied.
