An optical system disclosed to an embodiment of the invention includes first to seventh lenses sequentially arranged along an optical axis from the object side to the image side, wherein the first lens has a negative refractive power, and the third lens has a positive refractive power The object-side surface of the first lens may be concave, the object-side surface and the image-side surface of the third lens may be convex, and the third lens may be satisfied the following Equation 1: 0.5<f3/F<1.5 (In Equation 1, F denotes an effective focal length of the optical system, and f3 denotes a focal length of the third lens).

Optical system comprising first to seventh lenses sequentially arranged along an optical axis and camera module comprising the same

An optical system disclosed to an embodiment includes first to seventh lenses sequentially arranged along the optical axis from the object side to the image side, wherein the second lens has a positive refractive power, and the third lens has a negative refractive power, wherein the object-side and image-side surfaces of the second lens are convex, the image-side surface of the third lens is concave, and the first and third lenses satisfy the following equation 1: [Equation 1] 0.7<(SD L3S1)/(SD L1S1)<0.95 (in Equation 1, SD L1S1 means an effective radius of the object-side surface of the first lens, and SD L3S1 means an effective radius of the object-side surface of the third lens).
