Abstract: An optical image capturing system includes, 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 and a sixth lens element. The first lens element with positive refractive power has a convex object-side surface. The second lens element and the third lens element have refractive power. The fourth lens element with negative refractive power has a concave object-side surface and a convex image-side surface. The fifth lens element with positive refractive power has a convex object-side surface, wherein at least one inflection point is on at least one surface thereof. The sixth lens element with negative refractive power has a concave object-side surface. The surfaces of the fifth and the sixth lens elements are aspheric. The optical image capturing system has a total of six lens elements.

Abstract: A 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. The first lens element with positive refractive power has an object-side surface being convex in a paraxial region thereof. The second lens element with negative refractive power has an image-side surface being concave in a paraxial region thereof. The seventh lens element 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 image-side surface of the seventh lens element includes at least one convex shape in an off-axis region thereof. The object-side surface and the image-side surface of the seventh lens element are aspheric.
