ARRI Signature Primes
Ranging from 12mm to 280mm, the ARRI Signature Primes lenses offer a uniquely warm look that is characterized by smooth skin and crisp black. The Signature Primes are considered ARRI’s flagship lenses. This unique glass was born due to the high demand for the large format look. The most notable utilization of the Signature Primes was in 1917. Cinematographer Roger Deakins shot the whole movie on the ALEXA Mini LF with the Signature Primes. According to Deakins, the main characteristics of the Signature Primes are minimal breathings and distortion, together with a clean and sharp image. “I don’t like vignetting; I don’t like breathing…. Can’t stand flares,” said Deakins when he describes the main benefits the Signature Primes. Read more in the article: Large Format Cinematography: Roger Deakins Talks About the ALEXA Mini LF.
