Improving on the Zeiss Classic line, the Milvus primes inherit the best the Classic primes have to offer while updating with new optical designs. Consider the Milvus primes the newer, better Classic Zeiss primes. Their streamlined all aluminum body features a fully manual aperture control with integrated de-click option on the ZF.2 (Nikon) mount and an electronic aperture on the ZE (Canon) mount. When combined with the Duclos Cine-Mod®, the Milvus primes are the future of DSLR and light-weight, compact cinematography.
