NiSi 25mm ATHENA PRIME Full Frame Cinema Lens T1.9 (G Mount | No Drop In Filter)

The Athena Prime 25mm 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. NiSi designed the whole Athena Prime range to match weight and size across focal lengths, so switching lenses on a gimbal doesn't require rebalancing, and the 300° focus ring rotation with fluorescent focal scales is built for precise, repeatable focus pulls. This G Mount version does not include a drop-in filter slot.

• T1.9 maximum aperture: full-frame coverage with soft bokeh and strong background separation.
• 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.
• No drop-in filter: this G Mount version does not include the drop-in filter slot found on some other Athena Prime mounts.
