New optical standard for cinematography
Based on the latest in design methods, optical glass, and findings on suppression of reflexes and stray light Carl Zeiss and its partner ARRI have introduced a new generation of fast prime lenses for 35 mm film, the Ultra Primes.
Ultra Prime lenses come with large, easy-to-read calibrated scales, uniform diameters and position of focus and aperture drive rings, and uniform position of the exit pupil. Ultra Prime lenses are particularly robust and easy to service. The optical performance is superb, even wide open. Floating elements keep the optical performance up to the close-focusing limit. Distortion is well controlled and so is breathing, especially with the wider angle lenses, where it counts most.
The Zeiss/ARRI Ultra Primes currently are the largest set of cine prime lenses. And Carl Zeiss and ARRI are already working to add to it further.
New Optics
Floating Elements for outstanding close-up performance Lenses reach their highest performance at the focus setting for which they have been optimized. This is normally infinity.
Beneath that, the performance usually drops off, particularly through a considerable increase in image area curvature and increasing aperture aberrations. Because of this, most optics manufacturers limit the minimum close-up setting possibility of their lenses to prevent users from moving too far into this area of lesser performance.
With the ULTRA PRIME lenses, Carl Zeiss introduced and perfected an effective means against Floating Elements. This is a design principle in which lens groups move about each other during focusing, thereby correcting image area curvature. This principle must be taken into account not only in the optical design but also in the highly precise construction of the mechanical components. Both were achieved for the new ULTRA PRIME lenses allowing for close-up setting possibilities almost up to the front element of these lenses.
