Abstract
Official abstract text for this publication.
A photographing lens 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 and a fifth lens element. The first lens element with negative refractive power has a concave image-side surface. The second lens element has refractive power. The third lens element with positive refractive power has a convex object-side surface and a convex image-side surface. The fourth lens element with negative refractive power has a concave image-side surface, wherein an object-side surface and the image-side surface of the fourth lens element are aspheric. The fifth lens element with positive refractive power has a convex object-side surface and a convex image-side surface, wherein the object-side surface and the image-side surface of the fifth lens element are aspheric.
