The V60 objective lens and V80 objective lens, both adopt a triplet APO design, two of which are ED glass, which can effectively eliminate chromatic aberration and increase image clarity. The V60 native focal ratio is f/6, and the focal length is 360mm. The V80 native focal ratio is f/6.25, and the focal length is 500mm. V is equipped with three additional accessories that are adjustable to 60mm or 80mm scales through rotation.
