NiSi 18mm Aureus Prime Full Frame T1.4 Cinema Lens (PL Mount)

The NiSi Aureus Prime 18mm T1.4 Full Frame Cinema Lens (PL Mount) is a professional ultra-wide lens designed for full-frame cinema cameras. It delivers edge-to-edge clarity with a 46mm image circle, excels in low-light with a fast T1.4 aperture, and features near-zero focus breathing for precise cinematic control.

Cinematic Optical Quality

The advanced optical design includes ultra-low dispersion elements that minimise chromatic aberration and maintain high resolution across the frame. Multi-layer coatings reduce flaring and ghosting, helping preserve contrast in backlit or high-contrast scenes.

Creative Depth and Low-Light Flexibility

With a wide T1.4 aperture and 11-blade iris, the lens offers shallow depth of field, smooth bokeh, and strong low-light performance—ideal for handheld, gimbal, or drone setups where lighting is limited but image quality is critical.

Precision Focus Handling

A 300° focus rotation with smooth, calibrated resistance supports accurate manual focus pulls. Minimal focus breathing ensures consistent framing during shifts, enhancing narrative control without compromising composition.

Streamlined On-Set Workflow

The 18mm lens matches the Aureus Prime series in physical dimensions and gear positions—90mm front diameter, 86mm filter thread—for efficient rigging and fast lens swaps. Glow-in-the-dark dual-scale focus markings in feet and metres support visibility in low-light shoots.

Lightweight and Durable Build

Constructed with an all-metal housing, it weighs only 1300g—compact and balanced for demanding productions. Despite its wide angle, it doesn’t compromise on durability or image integrity.

Rear Filter Mount and System Integration

Includes a built-in rear filter mount compatible with NiSi PL filters, allowing compact creative setups. Designed to match the full Aureus Prime series optically, it maintains consistent colour and contrast when interchanging focal lengths on set.

Camera Compatibility

Supports all PL-mount cinema cameras, including ARRI, RED, Sony VENICE, and Blackmagic systems, as well as PL adapters with drop-in filters. It integrates seamlessly into professional production environments.
