NiSi 85mm ATHENA PRIME Full Frame Cinema Lens T1.9 (L Mount)
Key Features
The Athena Prime 85mm is built for micro-contrast control and low chromatic aberration at a bright T1.9 aperture, giving it soft bokeh and strong background separation for full-frame cinema work. This L Mount version includes a drop-in filter slot, letting you add ND filters or polarizers without mounting them on the front of the lens — faster to swap and less risk of front-element damage. Like the rest of the Athena Prime range, it's matched in weight and size to other focal lengths so switching lenses on a gimbal doesn't require rebalancing, and its 300° focus ring rotation with fluorescent focal scales is built for precise, repeatable focus pulls.
- T1.9 maximum aperture: full-frame coverage with soft bokeh and strong background separation.
- Drop-in filter mount (L Mount): add ND filters or polarizers without front-mounting, for faster swaps and less risk of front-element damage.
- Minimized focus breathing: field of view stays consistent from minimum focus distance to infinity for smoother focus pulls.
- Matched size and weight across the Athena Prime range: no rebalancing needed on a gimbal when switching lenses; 77mm filter thread shared across the series.
- 300° focus ring rotation: fluorescent focal scales for precise pulls in low light.
