    Abstract: A photographing lens assembly includes five lens elements, 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 and a fifth lens element. The first lens element with positive refractive power has an object-side surface being convex in a paraxial region. The second lens element has an object-side surface being concave in a paraxial region. The third lens element has an object-side surface being convex in a paraxial region. The fourth lens element has an object-side surface being concave in a paraxial region, wherein two surfaces thereof are both aspheric. The fifth lens element has an object-side surface and an image-side surface being both aspheric. At least one surface of the lens elements has at least one inflection point.

    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 optical imaging system includes ten lens elements which are, in order from an object side to an image side along an optical path: 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, a ninth lens element and a tenth lens element. Each of the ten lens elements has an object-side surface facing toward the object side and an image-side surface facing toward the image side. The second lens element has negative refractive power. The tenth lens element has negative refractive power, and at least one of the object-side surface and the image-side surface of the tenth lens element has at least one inflection point.
