ARRI Signature Prime Lens 21mm / T1.8 Meter Scale

Cinematic Excellence with the ARRI Signature Prime 21mm T1.8

The ARRI Signature Prime 21mm/T1.8 is a cornerstone of the large-format lens series, designed to deliver organic, emotionally resonant images. This wide-angle prime balances state-of-the-art optical precision with a gentle rendering style that texturizes the frame, producing natural skin tones and a creamy, non-distracting bokeh. With a fast T1.8 aperture, it provides exceptional shallow depth of field and a smooth focus fall-off that gives subjects a heightened presence.

Advanced Engineering and Lightweight Design

Constructed with machined magnesium lens barrels, the Signature Prime range is remarkably lightweight yet robust enough for demanding sets. The 21mm lens 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.

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 allow for superior optical performance that traditional PL mounts cannot achieve. It is fully compatible with the ARRI ALEXA 65, ALEXA LF, ALEXA Mini LF, and AMIRA cameras via LPL mounts, as well as various third-party systems and director's viewfinders.
