NiSi Athena Prime 50mm T1.9 (L-Mount)

Professional Cinematic Performance

The NiSi Athena Prime 50mm T1.9 (L-Mount) is a cornerstone of the Athena series, offering a natural perspective ideal for narrative filmmaking and portraiture. Designed for full-frame sensors with a 46mm imaging circle, this lens delivers unparalleled image quality by prioritizing micro-contrast control and minimizing chromatic aberration.

Superior Optical Design

With a fast T1.9 aperture, the Athena Prime 50mm provides a shallow depth of field and soft, aesthetic bokeh that ensures beautiful background separation. The optical construction is engineered to virtually eliminate focus breathing, maintaining a consistent frame while pulling focus between subjects.

All lenses in the range are matched in weight and dimensions, allowing for rapid lens changes on gimbals or drones without the need for rebalancing. The standardized 77mm filter thread and uniform placement of aperture and focus rings ensure that follow focus systems and matte boxes remain perfectly aligned.
