description The invention discloses an image system lens group, which comprises eight lens elements, namely a first lens element, a second lens element, a third lens element, a fourth lens element, a fifth lens element, a sixth lens element, a seventh lens element and an eighth lens element in sequence from an object side to an image side along an optical path. The first lens element has negative refractive power. The first lens element has an object-side surface being concave in a paraxial region thereof. The first lens element has an object-side surface having at least one inflection point at an off-axis position. The eighth lens element has positive refractive power. The eighth lens element has an object-side surface being convex in a paraxial region thereof. The eighth lens element has an image-side surface being concave in a paraxial region thereof. The image-side surface of the eighth lens element has at least one inflection point at an off-axis position. At least one of the second to seventh lenses has at least on
