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

Cinematic Excellence with the ARRI Signature Prime 40mm

The ARRI Signature Prime 40mm/T1.8 is a cornerstone of the large-format cine lens series, designed to deliver organic, emotionally engaging images. While providing state-of-the-art optical precision, this lens texturizes the large format with natural skin tones and a creamy bokeh that brings subjects to life. The fast T1.8 aperture allows for a shallow depth of field and a smooth focus fall-off, ensuring your subject maintains a heightened presence within the frame.

Advanced Magnesium Construction and LDS-2

Engineered for the demands of modern sets, the Signature Prime range features machined magnesium lens barrels. This makes the 40mm optic incredibly lightweight yet robust enough for rigorous professional use. Key technical features include:

• Next-generation LDS-2 Lens Data System for high-speed metadata.
• Absolute encoders for fast lens initialization.
• Near-telecentric design for optimal sensor performance.

Universal LPL Mount Compatibility

Equipped with the LPL (Large Positive Locking) mount, the 40mm Signature Prime is optimized for large-format sensors. The wider diameter and shorter flange focal depth enable a compact design and superior optical performance that traditional PL mounts cannot match. This lens is fully compatible with the ALEXA 65, ALEXA LF, ALEXA Mini LF, and via adapters, the entire ARRI camera lineup and various third-party systems.
