ARRI Signature Primes are designed for use with full format digital cinema cameras. Signature Primes exemplify state-of-the-art optical precision, yet they render organic, emotionally engaging images, gently softening and texturizing the large format with natural skin tones and creamy bokeh. A fast maximum aperture of T1.8 facilitates shallow depth of field and the smooth focus fall-off gives subjects heightened presence in the frame.
