NiSi AUREUS PRIME Cinema Lens 18mm T1.4 (PL-mount)

NiSi AUREUS PRIME Cinema Lens 18mm T1.4 (PL-mount).

The NiSi AUREUS PRIME Cinema Lens 18mm T1.4 (PL-mount) is a professional ultra-wide-angle lens designed to meet the rigorous demands of modern cinematography. Offering Full frame coverage with a huge 46mm image circle, this lens is designed for large format cinema cameras. The lens delivers impeccable image quality across the entire frame. With its ultra-wide-angle focal length of 18 mm and fast maximum aperture of T1.4, it excels in both expansive ambient and intimate low-light shots. This offers filmmakers creative flexibility and cinematic depth under all shooting conditions.

Whether capturing sweeping landscapes, complex architectural interiors or immersive handheld shots, the 18mm Aureus Prime lens renders each frame with clarity, contrast and character. The T1.4 aperture delivers exceptional low-light performance, ensuring shallow depth of field and beautiful bokeh even in wide-angle compositions. Combined with the lens' 11-blade Aperture, this results in smooth, natural blurred highlights and an organic visual aesthetic that enhances every frame.
The Aureus Prime 18mm lens is designed with advanced optical design and features ultra-low dispersion elements that significantly reduce chromatic aberration, Distortion and colour fringing. This ensures lifelike colour reproduction and edge-to-edge sharpness. Even at the maximum aperture of T1.4, the lens maintains exceptional resolution and contrast, retaining fine detail and consistent image quality from centre to edge.

The lens features NiSi's patented multilayer coatings that reduce ghosting and flare, while improving microcontrast and maintaining deep, rich blacks. These coatings ensure superior performance when working in high-contrast or backlit environments, making the 18mm lens ideal for a wide range of lighting conditions - from outdoor shots in the golden hour to atmospheric indoor scenes.
A notable feature of the 18mm Aureus Prime is its virtually no focus breathing - allowing filmmakers to create smooth focus transitions without changing the composition of the frame. This precise focus behaviour is crucial for storytelling, especially in dynamic scènes where emotional emphasis is created by subtle focus shifts.

With a focus rotation of 300° the lens offers long, smooth focus pulls with precisely calibrated resistance, allowing precise manual focus control for complex shots. This makes it ideal for both focus pullers on set and solo shooters demanding accuracy in high-resolution workflows.

The 18mm lens shares a uniform mechanical design with the rest of the Aureus Prime series. It features a consistent front diameter of 90mm and a filter thread of 86mm, ensuring compatibility with industry-standard matte boxes, follow focus systems and blur filters. Consistent equipment placement on all Aureus Prime lenses simplifies lens mounting and changing, streamlines on-set workflows and reduces downtime between setups.

The lens is built with a robust but lightweight, all-metal body and weighs only 1300 grams. This makes it perfect for handheld shooting, gimballed setups and Drone applications where balance and portability are essential. Despite its ultra-wide-angle focal length, the lens retains compact dimensions without compromising image quality or mechanical reliability.
The 18mm Aureus Prime has a built-in filter view at the rear, allowing Aureus PL ND filters, diffusion filters or creative filters to be used without thickening the front of the lens. This allows filmmakers to maintain a streamlined and balanced setup while expanding their creative toolbox.

For ease of use in challenging lighting conditions, the lens features glow-in-the-dark markings for the focus and aperture rings, allowing quick and precise adjustments even in dark environments. Dual-scale focus markings are available in both feet and metres, and the interchangeable design allows Users to adjust the lens to suit their regional or personal preferences.

The 18mm lens is compatible with all PL-mount cameras and works flawlessly with PL adapters, including those with built-in drop-in Filters. Whether shooting with the ARRI, RED, Sony VENICE or Blackmagic URSA system, the lens integrates effortlessly into any production environment, offering filmmakers professional flexibility and performance.
From grand establishing shots to stylised handheld shots, the NiSi Aureus Prime 18mm T1.4 Full frame Cinema Lens delivers powerful visual impact with technical precision. This lens is built not only for performance, but also for storytelling. It gives filmmakers the tools they need to create compelling, expressive and emotionally resonant images.

Whether used as a standalone ultra-wide-angle lens or as part of the complete Aureus Prime kit, the 18mm embodies the essence of cinematic artistry: light, clarity, depth and emotion.
