Photographing optical lens assembly, image capturing device and electronic device

摘要

A photographing optical lens assembly 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 positive refractive power has a convex object-side surface. The second lens element with negative refractive power has a convex object-side surface and a concave image-side surface. The third lens element has refractive power. The fourth lens element has refractive power, and an object-side surface and an image-side surface thereof are aspheric. The fifth lens element with negative refractive power has a concave image-side surface, wherein an object-side surface and the image-side surface thereof are aspheric, and at least one of the object-side surface and the image-side surface thereof has at least one inflection point.
