Beschreibung
Zusammenfassung:	An optical system includes: a first lens having negative refractive power; a second lens; a third lens; a fourth lens; a fifth lens; a sixth lens; and an image sensor configured to convert an image of a subject incident through the first to sixth lenses into electrical signals, wherein the first to sixth lenses are sequentially disposed from an object side of the optical system, and wherein TTL/(ImgH*2) 0.75 is satisfied, with TTL being a distance from an object-side surface of the first lens to an image plane of the image sensor and ImgH being half of a diagonal length of the image plane of the image sensor.
