Abstract: An optical photographing lens assembly includes nine lens elements which are, 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, a sixth lens element, a seventh lens element, an eighth lens element and a ninth lens element. Each of the nine lens elements has an object-side surface facing toward the object side and an image-side surface facing toward the image side. At least one lens element of the optical photographing lens assembly has at least one aspheric lens surface having at least one inflection point.
