Disclosed are an optical system and a camera module. The optical system sequentially includes, from an object side to an image side, a first lens, a reflective element and a second element group. The first lens has a positive refractive power, and allows propagation of light rays along a first optical axis. The reflective element changes light rays emitted from the first lens from propagating along the first optical axis to propagating along a second optical axis. The first lens and the reflective element constitute a first element group. The second element group has a positive refractive power. During an anti-shaking process, the position of an image plane of the optical system remains fixed, and the first element group rotates around a direction parallel to the second optical axis, an effective focal length f1 of the first lens and an effective focal length EFL of the optical system satisfy: 1.9<|f1/EFL|<3.0.
