ARRI Signature Prime Lens 15mm / T1.8 Meter Scale

Cinematic Excellence with the ARRI Signature Prime 15mm T1.8

The ARRI Signature Prime 15mm T1.8 represents the pinnacle of wide-angle large-format cinematography. Designed to accompany the ALEXA LF and ALEXA Mini LF, this lens delivers organic, emotionally engaging images that breathe life into every frame. While maintaining state-of-the-art optical precision, the 15mm Signature Prime softens the digital edge, providing natural skin tones and a creamy bokeh that sets it apart from clinical modern optics.

With a fast T1.8 aperture, this lens facilitates a shallow depth of field even at wide focal lengths. The smooth focus fall-off ensures subjects maintain a heightened presence, while the near-telecentric design guarantees optimal performance across various sensor types.

Advanced Magnesium Construction and LDS-2 Technology

The ARRI Signature Prime range is the first cine lens series to utilize machined magnesium lens barrels. This innovation makes the 15mm T1.8 incredibly lightweight yet robust enough for demanding sets. It also features the next-generation LDS-2 Lens Data System. With high data rates and absolute encoders, LDS-2 provides precise lens metadata, streamlining post-production and VFX workflows.

The LPL Mount Standard

Equipped with the LPL (Large Positive Locking) mount, the Signature Prime 15mm is optimized for large-format sensors. The wider diameter and shorter flange focal depth allow for a compact design and superior optical performance that traditional PL mounts cannot achieve. The LPL mount is compatible with ALEXA 65, ALEXA LF, ALEXA Mini LF, and via adapters, the entire ALEXA and AMIRA camera line.
