ARRI Signature Prime 18mm T1.8 Lens (Feet)

SKU | KK.0019189

Expected Delivery -

Accompanying the ALEXA LF camera is the ARRI Signature Prime 18mm T1.8 Lens (Feet) fitted with the ARRI LPL mount. While the Signature Primes exemplify state-of-the-art optical precision, they have been designed to render organic, emotionally engaging images, gently softening and texturising the large format with natural skin tones and creamy bokeh. A fast T-stop of T1.8 facilitates shallow depth of field and the smooth focus fall-off gives subjects heightened presence in the frame. The ARRI Signature Prime range is the first cine lens series to feature machined magnesium lens barrels, making the optics incredibly lightweight and robust. They are also the first to incorporate ARRI’s next-generation LDS-2 Lens Data System, with high data rates and absolute encoders for fast initialising. LDS-2 extends the possibilities of lens data and is being licensed to other lens and camera manufacturers.
