As part of ARRI's Signature Prime series, the 40mm T1.8 cinema lens is constructed to serve multiple sensor sizes, including full-frame, with its expansive image circle. The mid-range focal length of this lens is tailored to render a softer large-format aesthetic while maintaining sharp and vivid color contrast. Skin tones are rendered naturally, set against smooth background separation. The customizable magnetic rear net holder and an eleven-blade iris create a stunning bokeh and precise artistic control. Energy-efficient in design, the lens is easy-to-handle at 4.2 pounds and streamlined at 7 inches in length.

The ARRI Signature Prime 40mm T1.8 Cinema Lens is designed for high-end cinematic productions, offering exceptional optical performance and a natural aesthetic.
