ARRI Signature Prime Lens 40mm / T1.8 Meter Scale

Cinematic Excellence with the ARRI Signature Prime 40mm T1.8

The ARRI Signature Prime 40mm T1.8 is a cornerstone of the large-format cine lens series, designed to deliver organic, emotionally resonant images. While engineered with state-of-the-art optical precision, this lens avoids the clinical look of modern glass, instead providing natural skin tones and a creamy bokeh that adds a three-dimensional quality to every frame. The fast T1.8 aperture facilitates a shallow depth of field, allowing subjects to stand out with a smooth focus fall-off.

Advanced Magnesium Construction and LDS-2 Technology

Crafted with machined magnesium lens barrels, the Signature Prime range is remarkably lightweight yet robust enough for demanding professional sets. The 40mm T1.8 features the ARRI LDS-2 Lens Data System, offering high data rates and absolute encoders for near-instant initialization. This next-generation system streamlines post-production workflows and enhances on-set efficiency by providing precise lens metadata.

Universal LPL Mount Compatibility

Equipped with the LPL (Large Positive Locking) mount, this lens is optimized for large-format sensors. The wider diameter and shorter flange focal depth enable the fast T1.8 aperture and superior optical performance that would be impossible with traditional mounts. The LPL mount is compatible with the ALEXA 35, ALEXA LF, ALEXA Mini LF, and via adapters, a wide range of other professional cinema cameras and testing tools.
