ARRI Signature Prime Lens 150mm / T1.8 Feet Scale

Organic Images with Emotional Depth

The ARRI Signature Prime 150mm T1.8 is engineered to produce organic, emotionally engaging images that breathe life into large-format cinematography. While it delivers state-of-the-art optical precision, it is specifically designed to soften the digital edge, texturizing the frame with natural skin tones and creamy bokeh. The fast T1.8 aperture facilitates an incredibly shallow depth of field, while the smooth focus fall-off gives subjects a heightened presence within the frame.

Advanced Magnesium Build and LDS-2 Technology

As part of the first cine lens series to feature machined magnesium lens barrels, the 150mm Signature Prime is exceptionally lightweight and robust. It incorporates ARRI’s next-generation LDS-2 Lens Data System, featuring high data rates and absolute encoders for rapid initialization. This system extends the possibilities of lens metadata, streamlining workflows for both production and post-production teams.

Universal LPL Mount Compatibility

Equipped with the LPL (Large Positive Locking) mount, this lens is a vital component of ARRI’s large-format camera system. The wider diameter and shorter flange focal depth enable the lens to remain compact and lightweight while maintaining a fast T-stop. The LPL mount is an open standard, making the Signature Prime compatible with ALEXA 65, ALEXA LF, ALEXA Mini LF, AMIRA, and various third-party systems via dedicated mounts.
