Raynox Conversion Lens 0.5x zoom broadens the angle of view, and provides an enlarged area. The lens is made of high-index optical glass elements, with a new concept of lens design that uses a three-group lens formula. With anti-reflection coating on all surfaces of the element, it allows in more light for a brighter picture, and eliminates the strayed beams at the fringe of the lens, lessening the aberration effects. The wide angle converter offers a higher and sharper image quality.
