Abstract

An optical system, a lens module, and an electronic device are provide. The optical system includes, in order from an object side to an image side along an optical axis, a first lens with a negative refractive power, a second lens with a positive refractive power, a third lens with a negative refractive power, a fourth lens with a refractive power, a fifth lens with a positive refractive power, and a sixth lens with a negative refractive power. An object-side surface of the fifth lens has at least one inflection point. At least one of an object-side surface and an image-side surface of the sixth lens has at least one inflection point. The optical system satisfies the following expression: −9<f4/|f1|<3.5.
