Abstract
An imaging system lens assembly includes eight lens elements which are, in order from an object side to an image side along an optical path, a first lens element through an eighth lens element. The first lens element has negative refractive power. The object-side surface of the first lens element is concave in a paraxial region thereof and has at least one inflection point in an off-axis region thereof. The eighth lens element has positive refractive power. The object-side surface of the eighth lens element is convex in a paraxial region thereof. The image-side surface of the eighth lens element is concave in a paraxial region thereof and has at least one inflection point in an off-axis region thereof. At least one of the lens surface of at least one of the second through seventh lens elements has at least one inflection point in an off-axis region thereof.
