The NiSi ATHENA PRIME Rewind 50mm T1.9 Full Frame Cinema Lens (PL Mount) is a classic standard cine prime that blends vintage-inspired character with modern optical performance—perfect for filmmakers seeking a natural perspective with expressive visual style.

Designed for full-frame coverage, the 50mm focal length delivers a true-to-life field of view, making it ideal for portraits, dialogue scenes, and narrative storytelling. Its fast T1.9 to T22 aperture range provides excellent low-light capability and precise depth-of-field control, allowing for beautifully isolated subjects and smooth background falloff.

As part of the Rewind series, this lens offers a unique dual-look rendering, combining vintage aesthetics—such as distinctive bubble bokeh and warm, cinematic flares—with the sharpness and consistency expected from modern optics. This balance gives creators the flexibility to achieve a stylized cinematic look without sacrificing clarity.

Engineered for professional cinema use, it features 0.8 MOD gears and an extended 300° focus rotation, ensuring smooth and accurate manual focus control for precise focus pulling. The 80mm front outside diameter allows compatibility with standard matte boxes and accessories, while color matching with standard ATHENA primes ensures consistency across a full lens set.

Optically refined, the lens maintains minimal focus breathing and low chromatic aberration, delivering stable and clean visuals even during focus transitions. A 77mm filter thread adds versatility for attaching filters directly when needed.

For ease of use in global productions, the lens includes dual measurement markings in both feet and meters, supporting a wide range of professional workflows.

With its natural perspective, fast aperture, and cinematic rendering, the NiSi ATHENA PRIME Rewind 50mm T1.9 is an excellent choice for filmmakers looking for a dependable and character-rich standard lens.

Product Features in Detail

The NiSi ATHENA PRIME Rewind 50mm T1.9
The NiSi ATHENA PRIME Rewind 50mm T1.9 is a full-frame cinema prime lens designed for filmmakers and cinematographers who want the ability to shift between vintage-inspired character and modern optical precision within a single lens. The 50mm offers a standard perspective that closely mirrors natural human vision, making it one of the most versatile and frequently used focal lengths in narrative and commercial filmmaking.

Two Cinematic Looks from One Lens
The defining feature of the ATHENA PRIME Rewind 50mm is its ability to deliver two distinct optical personalities. Wide open at T1.9, the lens produces a warm, vintage character with amplified aberrations, softened resolution, and enhanced foreground and background blur complete with halo effects on highlights. As the aperture is stopped down, these characteristics progressively diminish. By T2.8, cinematographers reach a balanced sweet spot between stylisation and sharpness, and by T5.6 to T8, the lens behaves close to a modern, clinically clean cinema lens.

The Natural Storytelling Perspective
At 50mm, the Rewind delivers a field of view that closely matches natural human perception, creating images that feel intimate and true to life. This makes it an exceptional choice for dialogue-driven scenes, medium close-ups, and character-focused narrative work where emotional connection is paramount. With full-frame coverage and a 46mm imaging circle, the Rewind 50mm supports all modern large-format cinema cameras while retaining the organic barrel distortion and analogue warmth that define the Rewind series.

Pronounced Bubble Bokeh and Warm Flares
The 50mm is one of the two focal lengths in the Rewind set where the signature bubble bokeh is most pronounced, producing striking bright-edged highlights with darker centres at wide apertures. This creates a beautifully textured background rendering that adds visual interest and depth separation to every frame. Flare intensity is significantly increased over the standard Athena Prime, delivering warm-toned flares that add atmosphere and energy to backlit scenes. The Rewind 50mm maintains color rendering highly consistent with the standard ATHENA PRIME set, allowing seamless intercutting.

Professional Build and Workflow
The 50mm features matched weight and physical dimensions with all other Rewind focal lengths, enabling seamless lens changes without gimbal rebalancing or matte box adjustments. The 300-degree focus ring with fluorescent focal scales ensures precise focus pulls in low-light conditions, while the rear filter mount allows for quick gel and creative filter changes. Minimal focus breathing maintains a stable field of view during focus adjustments, and chromatic aberration levels remain unchanged from the standard Athena Prime, ensuring stylistic character without undesirable fringing artifacts.

A Versatile Creative Tool
Whether shooting intimate character studies, stylised commercial beauty work, or atmospheric narrative sequences, the NiSi ATHENA PRIME Rewind 50mm T1.9 provides filmmakers with a lens that combines the emotional intimacy of the standard focal length with the creative versatility of the Rewind’s dual-personality design. The ability to transition from vintage warmth to modern clarity within a single lens makes it an essential tool for productions seeking both character and precision.

One Lens. Two Cinematic Personalities
The Rewind delivers a film-inspired vintage character wide open, then transforms into a clean, modern cinema lens when stopped down, giving filmmakers two distinct looks from one lens.

Vintage Character with Modern Control
Through deliberate optical design, the Rewind simulates film-era lens characteristics including amplified aberrations, reduced resolution at wide apertures, and enhanced softness for an authentic vintage look without relying on actual old glass.

Classic 50mm Standard Perspective
Delivers a field of view that closely matches natural human perception, making it a versatile choice for dialogue scenes, medium close-ups, and narrative storytelling with full-frame coverage and a 46mm imaging circle.

Adjustable Stylization via Aperture
Vintage character is strongest at T1.9, progressively diminishes through T2.8 (a balanced sweet spot), and by T5.6–T8 the lens behaves close to a modern cinema lens, providing a creative dial for cinematographers.

Pronounced Bubble Bokeh
The 50mm is one of the two focal lengths where the Rewind’s signature bubble bokeh is most pronounced, producing striking bright-edged highlights at wide apertures that fade controllably by T4.0.

Warm, Expressive Flares
Flare intensity is significantly increased over the standard Athena Prime with a warm color tone, adding cinematic atmosphere to backlit scenes and practical lighting setups.

Color Consistent with Standard Athena Prime
The Rewind’s color rendering closely matches the standard Athena Prime, making it easy to intercut or mix both lens types on set without post-production color correction.

300° Focus Ring with Fluorescent Scales
Precision focus pulls are made easy with 300 degrees of rotation and fluorescent focal markings for visibility in low-light shooting environments.

Matched Weight and Size Across All Rewind Lenses
Seamless lens swapping without the need for gimbal rebalancing, rig adjustment, or matte box reconfiguration, saving valuable time on set.

Rear Filter Mount for Creative Flexibility
Built-in rear filter slot allows for quick gel and filter changes without disturbing the front of the lens, maintaining a streamlined workflow.

Minimal Focus Breathing
Ensures a consistent field of view during focus adjustments, critical for cinematic pull-focus work and professional video production.

No Added Chromatic Aberration
While aberrations are amplified for the vintage look, chromatic aberration levels remain unchanged from the standard Athena Prime, delivering style without undesirable fringing.
