ARRI Signature Prime Lens 18mm / T1.8 Meter Scale

Cinematic Excellence with the ARRI Signature Prime 18mm

The ARRI Signature Prime 18mm T1.8 is a cornerstone of the large-format cinematography ecosystem. Designed to accompany the ALEXA LF and ALEXA Mini LF, this lens delivers organic, emotionally engaging images that texturize the digital sensor with natural skin tones and a smooth focus fall-off. The fast T1.8 aperture enables a shallow depth of field, giving subjects a heightened presence within the frame.

Innovative Engineering and LPL Mount

Equipped with the LPL (Large Positive Locking) mount, the Signature Prime series overcomes the limitations of the traditional PL mount. This wider diameter and shorter flange focal depth allow for a compact, lightweight design without sacrificing optical speed or bokeh quality. The lens barrel is constructed from machined magnesium, making it incredibly durable for field use while remaining remarkably light.

Next-Generation Lens Data

This lens incorporates ARRI's LDS-2 Lens Data System. Featuring high data rates and absolute encoders, LDS-2 provides precise lens metadata for post-production and visual effects workflows. The near-telecentric optical design ensures consistent performance across various sensors, maintaining delicate flares and fine detail rendering.

• Compatible with ALEXA 65, ALEXA LF, ALEXA Mini LF, and AMIRA via LPL mount.
• Meter scale focus markings for precision pulling.
• Universal compatibility with third-party LPL adapters and viewfinders.
