   OVERVIEW   

exceptionally smooth

Arri Signature Primes helped define the early aesthetic of large-format digital cinematography, integrating seamlessly with the Arri LF and Mini LF cameras. With a T1.8 aperture, they deliver a deceptively smooth sharpness—resolute and detailed, but never harsh—paired with controlled flare and negligible breathing.

de facto choice

The color reproduction leans neutral, allowing DPs to sculpt their palette in post. They’ve become a go-to choice for high-profile streaming series and feature films transitioning to large-format capture, used by cinematographers like Greig Fraser and Roger Deakins for their ability to gracefully handle everything from natural light exteriors to meticulously lit interiors.
