Description
The ARRI Signature Primes are large-format prime lenses designed for full-frame, large format-sensors and Super 35. They produce organic images with pleasant, natural skin tones and a soft look for large format shooting. In addition, an attractive bokeh and fast aperture at T1.8 for shallower depth of field.
The smooth focus fall off allows highlighting of subject against the background. Also, the LPL-mount features ARRI LDS-2 lens-data compatibility. Consequently, this enables speedy lens setups and higher lens metadata rates.
Signature Primes are lightweight, constructed with magnesium housings with aluminium gear rings. Focus marks are in feet. It includes Anti-reflective coatings, light baffles and light traps to minimise internal flare. In addition, eleven iris blades produce smooth, round bokeh effects with minimal breathing. Finally, the Signature Primes are compatible with ARRI’s LDS-1 and Cooke’s /i Technology.
