Optical Characteristics

  • Native Look: Delivers natural image detail with stunning bokeh, gentle focus fall-off, and minimal focus breathing
  • Ensō Vintage Elements: Optional rear-mounted magnetic filters that allow cinematographers to modify the lens’s optical characteristics, offering three positive and three negative elements to achieve various vintage looks
  • Metadata Integration: Built-in chips provide real-time lens data (focus, iris, zoom) to compatible cameras, aiding in on-set monitoring and post-production workflows

ARRI Signature Primes

Designed for use with full-frame, large-format sensors, the versatile ARRI Signature Primes also cover Super 35. Dedicated LF Open Gate, and Super 35 Open Gate magnetic format masks enable you to switch between formats, and are included with the lens. Stockings, nets, and voile can be used for diffusion when mounted in the Signature Prime’s rear net holder. Eleven iris blades produce smooth, rounded bokeh effects, and a telecentric design minimizes breathing. The LDS-2 lens data system is backwards-compatible with ARRI’s LDS-1, and communicates with Cooke’s /i Technology.

Constructed with magnesium housings and aluminum gear rings, each Signature Prime is lightweight, water-resistant, and features focus marks in feet. Anti-reflective coatings, light baffles, and light traps help to minimize any internal barrel flare
