| Zusammenfassung: | The invention relates to an optical system, an image capturing module and terminal equipment. The optical system includes a first lens element with negative refractive power, an object-side surface being concave in a paraxial region thereof, and an image-side surface being concave in a paraxial region thereof; a second lens element with positive refractive power having an object-side surface being convex in a paraxial region thereof; a third lens element with refractive power; a fourth lens element with negative refractive power having an object-side surface being concave in a paraxial region thereof and an image-side surface being concave in a paraxial region thereof; a fifth lens element with positive refractive power having an object-side surface being convex in a paraxial region thereof and an image-side surface being convex in a paraxial region thereof; a sixth lens element with positive refractive power having an object-side surface being convex in a paraxial region thereof and an image-side surface bei |
