Abstract: An image capturing lens assembly includes six lens units which are, in order from an object side to an image side along an optical path: first through sixth lens units. Each lens unit of the first through third lens units and the fifth through sixth lens units is a single lens element. The fourth lens unit is a single lens element or is composed of two lens elements, and the fourth lens unit at least includes a front lens element. The total number of lens elements of the image capturing lens assembly is six to seven. The first lens unit has an image-side surface being concave in a paraxial region thereof. The third lens unit has an object-side surface being convex in a paraxial region thereof. The front lens element with negative refractive power has an image-side surface being concave in a paraxial region thereof.

Abstract: An imaging lens system includes seven lens elements which are, in order from an object side to an image side along an optical path, a first lens element, a second lens element, a third lens element, a fourth lens element, a fifth lens element, a sixth lens element and a seventh lens element. Each of the seven lens elements has an object-side surface facing toward the object side and an image-side surface facing toward the image side. The first lens element has negative refractive power. The image-side surface of the fifth lens element is convex in a paraxial region thereof. The sixth lens element has negative refractive power. The object-side surface of the sixth lens element is concave in a paraxial region thereof. At least one of the object-side surface and the image-side surface of at least one of the seven lens elements has at least one inflection point.

Abstract: An optical lens includes a first lens group and a second lens group. The first lens group is disposed between a magnified side and a minified side and has a negative refractive power. The second lens group is disposed between the first lens group and the minified side and has a positive refractive power. The optical lens is capable of forming an image at the magnified side. F/H>0.52, where F is an effective focal length, and H is an image height. A viewing angle is greater than 116.7 degrees.

Abstract: A fixed focal length lens includes a first lens group and a second lens group. The first lens group is disposed between a magnified side and a minified side and has a negative refractive power. The second lens group is disposed between the first lens group and the minified side and has a positive refractive power. The fixed focal length lens satisfies F/H>0.52, where F is an effective focal length of the fixed focal length, and H is an image height.
