Patent attributes
A photographing optical lens assembly includes seven 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 and a seventh lens element. The first lens element with positive refractive power has an object-side surface being convex in a paraxial region thereof and an image-side surface being concave in a paraxial region thereof. The second lens element has positive refractive power. The sixth lens element with positive refractive power has an image-side surface being convex in a paraxial region thereof. The seventh lens element with negative refractive power has an image-side surface being concave in a paraxial region thereof and including at least one convex critical point in an off-axis region thereof.
