An optical system (100), comprising: a first lens (L1) having negative refractive power, the object side surface (S1) being concave; a second lens (L2) having positive refractive power, the object side surface (S3) being convex; a third lens (L3) having positive refractive power, the object side surface (S5) being convex and the image side surface (S6) being convex; a fourth lens (L4) having positive refractive power; a fifth lens (L5) having negative refractive power, the object side surface (S9) being concave and the image side surface (S10) being concave; a sixth lens (L6) having positive refractive power; and a seventh lens (L7) having negative refractive power, the object side surface (S13) being concave and the image side surface (S14) being concave. The optical system (100) satisfies: -5≤f7/f≤-2.5, f7 being the effective focal length of the seventh lens (L7), and f being the effective focal length of the optical system (100).
