ZEISS Supreme Prime Radiance (SPR) lenses are a new set of 7 lenses that artistically emphasize ghosting (flares) and are consistent across the entire set. They are based on Supreme Primes with a warmer color tone. They are not simply the same lenses with the coatings removed. There is no loss of light and no uncontrolled “white-out.” Instead, Radiance lenses have newly formulated T* Blue coatings. While there are 13 focal lengths in a set of Supremes, a Radiance set consists of 7, from 21mm to 100mm, all T1.5. There will be limited production runs. read more…
