ARRI Signature Primes are designed to gently soften and smooth large-format texture, with flattering skin tones and smooth, soft falloff. They are sharp without a clinical look, with minimal chromatic aberration, well-controlled flare and consistent rendering from wide open.
Full Frame coverage is designed for ALEXA LF, Mini LF, ALEXA 35 and 265 with LPL mount. Lightweight magnesium body, uniform 114 mm front diameter, 0.8 MOD gear and LDS-2 metadata make work on set and in post-production easier.
