An optical system includes, in order from an object side to an image side, a front unit having positive refractive power, an aperture stop, and a rear unit having positive refractive power. The front unit includes, in order from the image side to the object side, a first aspheric lens, a first negative lens, and a first positive lens. The rear unit includes, in order from the image side to the object side, a second aspheric lens, a second negative lens, and a second positive lens. The first aspheric lens includes an aspheric surface having an inflection point in a section including an optical axis. A predetermined condition is satisfied.
