Abstract:
1. An optical photographing lens assembly comprising, in order from an object side to an image side: a first lens element having positive refractive power and an image-side surface being concave in a paraxial region thereof; a second lens element having positive refractive power; a third lens element with positive refractive power having an image-side surface being concave in a paraxial region thereof; a fourth lens element having refractive power; and a fifth lens element with refractive power having an image-side surface being concave in a paraxial region thereof, wherein both of an object-side surface and the image-side surface of the fifth lens element are aspheric, and at least one of the object-side surface and the image-side surface of the fifth lens element has at least one inflection point; wherein a number of lens elements with refractive power is limited to five, an axial distance between an object-side surface of the first lens element and an image plane is TL, a maximum image height of the optical photographing lens assembly is ImgH, and the following condition is satisfied:
