Zeiss are one of the longest running optics manufacturers around. The Zeiss Ultra Primes are sharp lenses, with a dramatic fall off. They have a contrasty look to them. Compact, reasonably light and have a T1.9 rating, these lenses are a great affordable alternative to the Master Primes and beautiful lenses to work with. Perfect for commercial work and feature films looking for a solid set of lenses that give clarity and sharpness and with a huge range of focal lengths.
