ARRI Signature Prime Lens 125mm / T1.8 Meter Scale

Cinematic Excellence with the ARRI Signature Prime 125mm T1.8

The ARRI Signature Prime 125mm T1.8 is a cornerstone of the large-format cinema lens range, specifically engineered to complement the ALEXA LF and ALEXA Mini LF systems. While providing state-of-the-art optical precision, this lens is celebrated for its ability to render organic, emotionally engaging images. It gently softens and texturizes large-format sensors, delivering natural skin tones and a creamy, sophisticated bokeh that brings subjects to life.

Advanced Magnesium Construction and LDS-2 Technology

Innovation meets durability in the Signature Prime series. The 125mm lens features a machined magnesium lens barrel, making it remarkably lightweight yet robust enough for demanding sets. It incorporates ARRI's next-generation LDS-2 Lens Data System. With high data rates and absolute encoders, LDS-2 ensures fast initialization and provides precise lens metadata, streamlining post-production workflows and VFX integration.

The LPL Mount Standard

Equipped with the LPL (Large Positive Locking) mount, the 125mm Signature Prime optimizes performance for large-format sensors. The wider diameter and shorter flange focal depth allow for a fast T1.8 aperture and superior optical characteristics that were previously unattainable with the standard PL mount. This lens is compatible with ARRI ALEXA 65, LF, Mini LF, and AMIRA cameras via LPL mounts, as well as various third-party systems.
