An optical system, sequentially comprising from an object side to an image side: a first lens having negative refractive power; a second lens having negative refractive power; a third lens having positive refractive power; a fourth lens having positive refractive power, both the object side surface and the image side surface of the fourth lens being convex; a fifth lens having negative refractive power, both the object side surface and the image side surface of the fifth lens being concave; and a sixth lens having positive refractive power, both the object side surface and the image side surface of the sixth lens being convex. The optical system satisfies the following relationship: −47<27, wherein f45 represents a combined focal length of the fourth lens and the fifth lens, and f represents an effective focal length of the optical system.
