Abrégé

The present application provides an optical system, a lens module, and an electronic device. The optical system sequentially comprises first to sixth lenses from an object side to an image side in an optical axis direction; the first lens has positive refractive power, and a paraxial region and a near circumferential region of an object side surface of the first lens are both convex surfaces; the second lens to the sixth lens all have refractive power; the optical system satisfies the conditional expression: 3≤(Y62*TL)/(ET6*f)≤10, wherein Y62 is the maximum optical effective radius of an image side surface of the sixth lens, TL is the on-axis distance from the object side surface of the first lens to an imaging surface of the optical system, ET6 is the thickness of the edge of the sixth lens in the optical axis direction, and f is the effective focal length of the optical system. By arranging a six-lens structure, the refractive power and the surface types of the six optical lenses are reasonably configured, and the optical system satisfies the relational expression above, so that the long-focus characteristic and lightness and thinness can be realized while the high-quality imaging quality is ensured.
