Abstract
An optical photographing lens assembly includes seven lens elements which are, in order from an object side to an image side along an optical path, a first lens element through a seventh lens element. Each of the seven lens elements has an object-side surface facing toward the object side and an image-side surface facing toward the image side. The object-side surface of the second lens element is convex in a paraxial region thereof. The sixth lens element has positive refractive power. The object-side surface of the seventh lens element is convex in a paraxial region thereof. At least one of the object-side surface and the image-side surface of at least one of the seven lens elements has at least one inflection point in an off-axis region thereof.
