The Arri / Zeiss 135mm LDS Master Prime T1.3 lens weighs 2.8 kg with a front diameter of 114 mm and a close focus distance of 1 m. Arri's Master Primes are a new generation of fast, revolutionary and unique fixed focal length lenses, offering unprecedented resolution, incredible contrast and virtually no breathing effect. A wide T1.3 aperture allows filming in low light or ambient light for more natural shots, creating the cinematic look of an extremely shallow depth of field. Its integrated Lens Data System (LDS) displays in real time the lens status and depth of field information on the video assist or on a dedicated lens data screen, and is particularly useful when using a crane or a Steadicam.
