Cinematographers have long appreciated the advantages of prime lenses. Their smaller, lighter design makes them ideal for handheld camerawork. Built with fewer optical elements, primes have less glass-to-air surfaces, so images have greater clarity and brilliance and are less prone to flare and ghosting. DigiPrime® lenses have been designed to deliver pristine images that are more desirable and visually pleasing than those achieved with any other lens.
