PHOTOGRAPHING LENS ASSEMBLY, IMAGE CAPTURING UNIT AND ELECTRONIC DEVICE

摘要

A photographing lens assembly includes, in order from an object side to an image side, a first lens element, a second lens element, a third lens element, a fourth lens element, a fifth lens element and a sixth lens element. The first lens element with positive refractive power has an object-side surface being convex in a paraxial region thereof. The second lens element has negative refractive power. The third lens element has positive refractive power, wherein both surfaces thereof are aspheric. The fourth lens element has refractive power, wherein both surfaces thereof are aspheric. The fifth lens element has negative refractive power, wherein both surfaces thereof are aspheric. The sixth lens element with positive refractive power has an object-side surface being concave in a paraxial region thereof and an image-side surface being convex in a paraxial region thereof, wherein both of the two surfaces are aspheric.
