Abstract
The optical system disclosed in the embodiment includes first to eighth lenses disposed along an optical axis, the first lens has positive refractive power and the eighth lens has negative refractive power, an object-side surface of the first lens is convex and a sensor-side surface is concave, an object-side surface of the fifth lens is concave and a sensor-side surface is convex, an object-side surface of the third lens has the minimum effective aperture among the lens surfaces, and the object-side surface of the eighth lens has a the maximum effective aperture among the lens surfaces, an average value of effective apertures of the both sides of the second lens is smaller than an average value of effective apertures of the both sides of the third lens, the sensor-side surface of the eighth lens has a concave and has an inflection point, and the following equation satisfies: 0.5<TTL/ImgH<3 (TTL is an optical axis distance from an apex of the object-side surface of the first lens to an image surface of a sensor, and ImgH is ½ of a maximum diagonal length of the image sensor).
