Nisi Aureus Prime 50mm T1.4 - PL-Mount

With the AUREUS PRIME T1.4 Cinema Lens series, NiSi presents a new series of high-quality full-frame cinema lenses. Developed for maximum reliability and first-class image quality, the AUREUS PRIME lenses are suitable for feature film and TV productions as well as documentaries and commercials.

Wide range of focal lengths for creative flexibility

The series comprises five focal lengths: 18mm, 24mm, 35mm, 50mm and 85mm. Each lens has a T1.4 aperture, a 46mm image circle and a compact, uniform housing for efficient workflows.

Cinematic optics & fast T1.4 aperture

The AUREUS PRIME lenses are optimized for full-frame and medium format sensors and deliver superior low-light performance. The T1.4 aperture enables precise depth control, while the 11-blade iris diaphragm ensures a soft, natural bokeh. Contrast and sharpness remain constant across the entire aperture range from T1.4 to T22.

High-precision optical design

By using ultra-low dispersion elements, AUREUS PRIME lenses minimize chromatic aberration, distortion and colour fringing. Advanced coatings reduce flare and ghosting and ensure high contrast with neutral color rendition for clear, undistorted images.

Minimal focus breathing & precise control

Special attention is paid to reducing focus breathing so that the image section hardly changes when the focus is shifted. The 300° focus ring enables precise, repeatable manual focusing - a must for high-resolution cinema productions.

Compact design for a seamless workflow

All lenses in the series share a front diameter of 90mm, an 86mm filter thread and an average weight of 1300g. This facilitates quick lens changes without rebalancing the camera rig. Identical positions of the focus and aperture adjustment rings ensure maximum compatibility with accessories. In addition, luminous markings enable easy operation in poor lighting conditions.

The lenses are supplied with interchangeable focus scales (feet or meters), which can be changed easily and without tools.

Rear filter holder for creative possibilities

An integrated rear filter holder supports ND, diffusion and effect filters. This is particularly practical for use with drones, gimbals or handheld cameras, where weight and balance play a major role.

Compatibility & connections

The AUREUS PRIME series is available in PL mount and supports a flange distance of 16.1mm to 19.8mm, ensuring compatibility with most PL mount cameras and adapters.

Perfectly compatible with NiSi ATHENA PRIME

The AUREUS PRIME series ideally complements the NiSi ATHENA PRIME lenses. Both series offer comparable optical characteristics and harmonious color rendition, so that different focal lengths can be easily combined.
