Abstract
A wide-angle lens, an image capturing device and an electronic device. The wide-angle lens includes in sequence from an object side to an image side along an optical axis: a first lens with a negative focal power, an image side surface of the first lens is concave at the optical axis; a second lens with a positive focal power, an object side surface of the second lens is convex at the optical axis, and an image side surface of the second lens is convex at the optical axis; a third lens with a focal power; a fourth lens with a positive focal power, an image side surface of the fourth lens is convex at the optical axis; a fifth lens with a negative focal power, an object side surface of the fifth lens is convex at the optical axis, an image side surface of the fifth lens is concave at the optical axis, and at least one of the object side surface and the image side surface of the fifth lens includes at least one inflection point; and an optical stop disposed between the first lens and the second lens; one of the first lens to the fifth lens is a glass lens.
