An optical photographing lens includes two lens groups including six lens elements. The two lens groups are, in order from an object side to an image side, a first and a second lens groups. The six lens elements are, in order from the object side to the image side, a first lens element through a sixth lens element. A focal length adjusting process is performed by changing an axial distance between the lens groups for varying a focal length of the optical photographing lens. The second lens group moves relative to the first lens group during the focal length adjusting process. At least one lens surface of the optical photographing lens has at least one inflection point always located within an optically effective area during the focal length adjusting process. The second lens element has negative refractive power.
An optical photographing lens comprising two lens groups, the two lens groups comprising six lens elements, the two lens groups being, in order from an object side to an image side along an optical path, a first lens group and a second lens group, the six lens elements being, in order from the object side to the image side along the optical path, 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, a total number of lens elements of the optical photographing lens is six, and each of the six lens elements having an object-side surface facing toward the object side and an image-side surface facing toward the image side;
