    Abstract: A photographing optical lens system includes at least six lens elements, wherein the photographing optical lens system includes at least one cemented lens group cemented by two of the lens elements adjacent to each other. The at least one cemented lens group includes, in order from an object side to an image side, a first cemented lens element, a cemented layer and a second cemented lens element. The first cemented lens element has a cemented image-side surface being aspheric. The cemented layer has a cemented object-side surface and a cemented image-side surface. The second cemented lens element has a cemented object-side surface being aspheric. An aspheric coefficient of the cemented image-side surface of the first cemented lens element is different from an aspheric coefficient of the cemented object-side surface of the second cemented lens element. One of the lens elements closest to an imaged object has positive refractive power.
