NiSi Athena Prime Rewind: vintage character and modern precision from one lens set

NiSi's intriguing new Athena Prime Rewind set lets cinematographers dial between vintage aberrations and clinical sharpness simply by adjusting aperture.

NiSi has announced the Athena Prime Rewind lens set, a five-lens full-frame cinema set designed to give cinematographers two distinct optical personalities from a single system. The kit covers 14mm T2.4, 25mm T1.9, 35mm T1.9, 50mm T1.9, and 85mm T1.9, and ships in a purpose-built hard case with PL-mount.

Aperture-driven character

NiSi has been adding character to the Athenas since release with various new iterations, and is looking to offer the best of both worlds here via aperture-driven changes in character. It's an increasingly crowded market, but the pitch is that their flexible characteristics effectively give you two lenses in one.

Wide open at T1.9, the lenses produce a warm vintage look with amplified aberrations, softened resolution, enhanced bokeh, and halo effects on highlights. Stop down to T2.8 and you hit a sweet spot and what the company says is a balance between stylization and sharpness. Carry on to T5.6 to T8 and the lenses behave close to a modern, clean cinema optic, very much in the vein of the mainstream Athena Primes.

The practical upside of this is that a DP can shift the visual feel of a shot without swapping glass or reaching for diffusion filters.

Bubble bokeh and Athena compatibility

At wide apertures, the Rewind produces bubble bokeh, out-of-focus highlights with bright edges and darker centers. These are most pronounced on the 35mm and 50mm focal lengths. The effect fades predictably by around T4.0. Flare intensity is significantly higher than the standard Athena Prime, with warm-toned flares suited to backlit scenes and practical light sources. Barrel distortion is retained across all focal lengths, contributing to the analog texture the design is going for, while chromatic aberration levels are unchanged from the standard Athena Prime. 

Continuity with the standard lens kit is important, and the Rewind is designed to match the color rendering of the standard Athena Prime. NiSi says cinematographers can freely intercut between Rewind and standard Athena lenses without extensive color correction. This sets it apart from the Athena Prime Tuned variant, which shifts toward yellow-green tones; the Rewind stays neutral.

Build

The kit offers a 46mm imaging circle for full-frame and large-format coverage. Dimensions and weight are matched across all five focal lengths, so lens changes won't require gimbal rebalancing or matte box adjustments. Each lens includes a 300-degree focus ring with fluorescent focal scales for low-light focus pulling, a rear filter mount, and minimal focus breathing.

Pricing and availability 

The Athena Prime Rewind is available through authorized NiSi cinema dealers worldwide, as a complete five-lens kit ($5999) or individually ($1269, with the 14mm priced separately at $1399).
