Abstract
The present disclosure relates to an optical system, an image acquisition module and an electronic device. The optical system includes, successively in order from an object side to an image side: a first lens having a negative refractive power; a second lens having a refractive power, an object side surface thereof being convex; a third lens having a positive refractive power, an image side surface thereof being convex; a fourth lens having a negative refractive power; a fifth lens having a positive refractive power; a sixth lens having a positive refractive power, an image side surface thereof being convex; a seventh lens having negative refractive power, an object side surface thereof being concave. The optical system satisfies the following condition: 0<100/(f2*|f1|)≤2.0 mm; where f2 is an effective focal length of the second lens, and f1 is an effective focal length of the first lens.
