Where can I buy the 8mm of ARRI/ZEISS ULTRA 16 series

The art of cinematography is closely tied to the art of creating the cinematographer's tools. The art of successful lens design has now been advanced with the introduction of a new set of high speed, wide angle lenses: the Ultra 16 lenses. Like the Master Primes, the Ultra 16 lenses combine high speed with outstanding optical performance. With a widest stop of T1.3 they allow shooting in low or available light, so are easy on the lighting budget, create more natural looking images and provide the cinematic look including, where necessary, a shallow depth of eld. Equaled by no other Super 16 lens in optical performance, they join the other ARRI/Zeiss lenses in elevating the Super 16 image to its highest possible quality.
