The ZEISS Supreme Radiance Primes offer everything that the original Supreme Primes do: Performance, size, weight, closest focusing distance and resolving power are unchanged, but beautiful flare effects are added. ZEISS has developed a new optical coating that delivers images with a beautiful blue flare/ghosting character reminiscent of the Bausch & Lomb Super Baltars. Zeiss Supreme Primes are popular for their small size, high resolving power, full field coverage, fast maximum aperture, consistency, excellent near focus and ZEISS quality and reliability. With the addition of the Radiance with its marvellous diffused light character, these lenses are unbeatable.
