ARRI Signature Prime Lens 18mm / T1.8 Feet Scale

Cinematic Excellence with the ARRI Signature Prime 18mm

The ARRI Signature Prime 18mm T1.8 is a cornerstone of modern large-format cinematography. Designed to accompany the ALEXA LF and ALEXA Mini LF, this wide-angle prime delivers organic, emotionally engaging images that breathe life into every frame. While it offers state-of-the-art optical precision, it avoids the clinical look of many modern lenses, instead providing natural skin tones and a creamy bokeh that gently texturizes the large-format sensor.

Advanced Optical Design and Build

With a fast T1.8 aperture, the 18mm Signature Prime facilitates a shallow depth of field and a smooth focus fall-off that gives subjects a heightened presence. The lens features a machined magnesium lens barrel, making it remarkably lightweight yet robust enough for the rigors of professional production. Its near-telecentric design ensures optimal results across all sensors, covering image circles up to 46mm.

Next-Generation Connectivity

This lens is at the forefront of technology, incorporating the ARRI LDS-2 Lens Data System. With high data rates and absolute encoders, LDS-2 allows for near-instant initialization and provides critical metadata for complex visual effects and post-production. The LPL mount ensures compatibility with the entire ARRI large-format ecosystem, including ALEXA 65, LF, and Mini LF cameras.
