ARRI Signature Prime Lens 25mm / T1.8 Meter Scale

Cinematic Excellence with the ARRI Signature Prime 25mm T1.8

The ARRI Signature Prime 25mm T1.8 is a cornerstone of the large-format cine lens range, designed to deliver organic, emotionally engaging images. While many modern lenses focus solely on clinical sharpness, the Signature Prime series texturizes the frame 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, creating a heightened sense of presence within the large-format canvas.

Innovative Magnesium Construction and LDS-2 Technology

Engineered for the rigors of professional production, the 25mm Signature Prime features a machined magnesium lens barrel. This choice of material makes the optic remarkably lightweight yet robust, easing the burden on camera operators and gimbal systems. It also incorporates the ARRI LDS-2 Lens Data System, which utilizes absolute encoders and high data rates to provide precise lens metadata instantly upon initialization.

The LPL Mount Standard

Equipped with the LPL (Large Positive Locking) mount, this lens is optimized for the ALEXA LF, ALEXA Mini LF, and other high-end cinema cameras. The LPL mount's wider diameter and shorter flange focal depth enable optical designs that were previously impossible with the traditional PL mount, resulting in faster T-stops and superior image quality. Through the use of LPL mounts, these lenses are compatible with the entire ALEXA family and AMIRA cameras, as well as third-party systems.
