NiSi 85mm Aureus Prime Full Frame T1.4 Cinema Lens (PL Mount)

The NiSi Aureus Prime 85mm T1.4 Full Frame Cinema Lens (PL Mount) is a professional telephoto prime lens designed for full-frame sensors, offering exceptional subject isolation, a fast T1.4 aperture for low-light performance, and minimal focus breathing—ideal for cinematic portraiture, narrative filmmaking, and precise manual focus control.

Telephoto Performance and Subject Separation

With an 85mm focal length and T1.4 aperture, this lens delivers flattering compression and shallow depth of field. It’s suited for close-ups and emotional storytelling, allowing subjects to stand out against a smoothly rendered background.

Low-Light Capability and Cinematic Bokeh

The wide T1.4 aperture excels in low-light conditions while producing soft, circular bokeh through its 11-blade iris—ideal for evening shoots, interviews, or mood-heavy scenes where light is limited but visual impact is essential.

Full-Frame Coverage with 46mm Image Circle

Designed for large sensor cameras, the 85mm covers a 46mm image circle, ensuring clean edge-to-edge sharpness and eliminating vignetting or optical falloff—helping cinematographers maintain visual consistency across a range of camera systems.

Precise Manual Focus with Minimal Breathing

A 300° focus rotation offers smooth, detailed focus pulls, while near-zero focus breathing ensures consistent framing during shifts—solving common issues in dialogue or rack-focus scenes.

Robust Yet Lightweight Build

Weighing 1300g, the precision-machined metal housing is durable for professional use yet light enough for handheld rigs or gimbals. It shares a consistent 90mm front diameter and 86mm filter thread with other Aureus Primes for seamless rig integration.

Rear Filter Slot and Colour Consistency

The built-in rear filter system allows for drop-in ND or diffusion filters without adding bulk to the front. Colour rendition remains accurate and matched across the Aureus and Athena series, maintaining skin tone fidelity and tonal balance throughout your project.

Operator-Friendly Features

Dual interchangeable glow-in-the-dark focus scales (feet or metres), standardised gear positions, and a neutral image profile make the 85mm easy to use on fast-paced sets—ideal for multicam configurations or multi-operator teams.

Versatile PL Mount for Broad Compatibility

Supports standard PL-mount systems and adapters with drop-in filters, offering flexibility across different camera builds and environments.

This lens is purpose-built for professionals who need reliable optical quality, mechanical consistency, and artistic control in cinematic applications.
