ARRI Signature Primes are designed specifically for use with the ARRI ALEXA LF large format digital cinema camera. While Signature Primes exemplify state-of-the-art optical precision, they have been designed to render organic, emotionally engaging images, gently softening and texturizing the large format with natural skin tones and creamy bokeh. A fast maximum aperture of T1.8 facilitates shallow depth of field and the smooth focus fall-off gives subjects heightened presence in the frame.
These lenses are fitted with the ARRI LPL mount, optimized for large-format sensors. A wider diameter and shorter flange focal depth allows the ARRI Signature Prime lenses and all future large-format optics to be small and lightweight, with a fast T-stop and pleasing bokeh. This combination of features would not be possible within the confines of the typical PL lens mount.
The ARRI Signature Prime range is the first cine lens series to feature machined magnesium lens barrels, making the optics incredibly lightweight and robust. They are also the first to incorporate ARRI’s next-generation LDS-2 Lens Data System, with high data rates and absolute encoders for fast initializing. LDS-2 extends the possibilities of lens data and is being licensed to other lens and camera manufacturers.
