Nisi Optics | Aureus Prime | 18mm | T1.4 Full Frame | Lens | PL |

Engineered for consistent sharpness, contrast, and color reproduction, the NiSi AUREUS PRIME 18mm T1.4 Full-Frame/VV Cinema Lens is an ARRI PL-mount lens that delivers clean images, ideal for digital post-production workflows. Its 11-blade iris creates natural background blur and smooth, rounded bokeh while ensuring a crystal-clear view of the subject in focus. With minimal focus breathing and 300° focus throw rotation, the AUREUS PRIME delivers precise depth control for dynamic compositions.

Featuring an ultrafast T1.4 maximum aperture and glow-in-the-dark markings, the lens excels in low-light conditions. Its ultra-low dispersion elements and advanced coatings minimize chromatic aberration, distortion, color fringing, flaring, and ghosting, maintaining reliable color rendering and contrast. The lens sports a 90mm front outside diameter, an 86mm front filter thread, and a built-in rear filter holder, allowing the integration of lightweight filtration close to the camera body for balance-dependent setups.

The AUREUS PRIME line features uniform housing, weight, and gear positioning, allowing each focal length to be swapped without needing stabilizer rebalancing or camera rig adjustment. They also share similar optical and tonal characteristics with the NiSi ATHENA PRIME lens line, allowing their incorporation into existing lens sets.
