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

Professional Full-Frame Cinema Performance

The NiSi Athena Prime 50mm T1.9 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 exceptional clarity and micro-contrast control while maintaining ultra-low chromatic aberration for pristine image quality.

Consistent Cinematic Workflow

Efficiency on set is paramount. All lenses in the Athena Prime series are matched in weight and size, allowing for rapid lens changes without the need to rebalance your gimbal or stabilizer. The standardized 77mm filter thread and uniform positioning of the aperture and focus rings ensure that follow focus systems and matte boxes remain perfectly aligned across the entire range.

Precision Control and Creative Bokeh

With a fast T1.9 maximum aperture, the NiSi 50mm produces a soft, pleasing bokeh that creates beautiful background separation. The lens is engineered to minimize focus breathing, ensuring a consistent field of view during critical focus pulls. For precision handling, the focus ring features 300 degrees of rotation and fluorescent focal scales, making it easy to operate in low-light environments.

Advanced Features for Filmmakers

The E-mount version includes a drop-in filter mount, providing a streamlined workflow for managing exposure and creative effects without bulky external hardware. Whether you are shooting a feature film or a high-end commercial, the NiSi Athena Prime 50mm T1.9 provides the reliability and optical excellence required for professional productions.
