Large Format ARRI Signature Prime lens.  Supplied as standard with LPL mount.

The Arri Signature Prime lenses offer a unique look never seen before in cinema. Warm, smooth skin; open shadows and crisp blacks; and bokeh like looking through a window in the rain. The timeless look of Signature will never go out of style.

ARRI introduces a complete large-format system that meets and exceeds modern production requirements, delivering unprecedented creative freedom. Based on a large-format 4K version of the ALEXA sensor, the system comprises the ALEXA LF camera, ARRI Signature Prime lenses, LPL lens mount and PL-to-LPL adapter. These system elements have been designed to take fullest advantage of the enlarged sensor, while also offering compatibility with existing lenses, accessories and workflows.
