Accompanying the ALEXA LF camera are 16 large-format ARRI Signature Prime lenses, ranging from 12 mm to 280 mm
and fitted with the ARRI LPL mount. While the 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 T-stop of T1.8 facilitates shallow depth of field and the smooth focus fall-off
gives subjects heightened presence in the frame.
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 ARRIs 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.
