The brand new ARRI/ZEISS Master Prime 12 combines an extreme wide angle with the highest optical quality and a fast speed of T1. 3 for the creation of truly unique images. One of the unmatched strengths of the ARRI/ZEISS prime lens program for digital and film cameras is the availability of extreme wide angle lenses, including the Ultra 16 lenses at 6, 8, 9. 5, 12 and 14mm, the Ultra Primes at 8, 10, 12 and 14mm and the Master Prime 14mm. [. . . ] The expansion of optical technologies into previously impossible designs has resulted in individual lenses and lens sets with unique qualities for every situation on the set. With the ARRI/ZEISS Master Prime 12, ARRI now offers an extreme wide angle lens that is fast with Master Prime optical quality for unique shots. Camera 41 ARRI/ZEISS masterPrime ATechnologicalChallenge Even five years ago, the creation of a 12mm lens at T1. 3 with Master Prime optical quality would have been technologically impossible. However, recent advances in high tech optics design, testing and manufacturing have allowed ARRI and ZEISS to start thinking about new and innovative lens designs. One of the main contributors to achieving such a unique combination of qualities was the use of aspherical lens elements. Aspherical lens elements have been used for a while now in many ARRI/ZEISS primes because of their ability to reduce size and weight while improving image quality. After a number of optical redesigns it became clear that the Master Prime 12 required two aspherical elements in order to reach the desired optical quality. Furthermore, the aspherical front element had to be of a size that exceeded anything incorporated into cine lenses before. Luckily, the creation of large aspherical lens elements is a technology that has been aggressively developed by ZEISS's Semiconductor and Nanotechnology business units. With their assistance it was possible to create such a lens element and to develop the necessary special testing instrumentation. A new pinnacle in optical design and manufacturing has been reached with the Master Prime 12.
