    Abstract: An optical photographing 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. Each of the seven lens elements of the optical photographing lens assembly 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 first lens element is concave in a paraxial region thereof. The object-side surface of the first lens element is aspheric and has at least one critical point in an off-axis region thereof.

    Abstract: An imaging lens assembly includes a plastic barrel and an imaging lens set. The plastic barrel includes an object-side aperture and a first annular surface. The imaging lens set includes a plurality of optical elements, wherein at least one of the optical elements is a plastic lens element, and the plastic lens element includes an effective optical portion, a peripheral portion, a second annular surface, and an object-side connecting surface. The peripheral portion is formed around the effective optical portion. The second annular surface is formed on an object-side surface of the plastic lens element and surrounds the effective optical portion. The object-side connecting surface is formed on the object-side surface of the plastic lens element and surrounds the effective optical portion, and the object-side connecting surface is connected with one of the optical elements disposed on an object side of the plastic lens element.
