Cinematic Excellence with the NiSi Athena Prime 40mm T1.9

The NiSi Athena Prime 40mm T1.9 (E-Mount) is a high-performance cinema lens designed for full-frame sensors, offering a 46mm imaging circle that covers most modern professional cameras. This 40mm focal length provides a natural perspective, making it an essential tool for narrative filmmaking, documentaries, and commercial productions.

Superior Optical Performance

Engineered for maximum micro-contrast control and ultra-low chromatic aberration, this lens delivers exceptional image clarity and fine detail. The fast T1.9 aperture ensures excellent low-light performance and produces a soft, pleasing bokeh that creates beautiful background separation for a truly cinematic look.

Minimized Focus Breathing

One of the standout features of the Athena Prime series is the minimized focus breathing. Whether pulling focus from the minimum distance to infinity, the field of view remains remarkably consistent, ensuring your audience stays immersed in the story without distracting shifts in composition.

The standardized 77mm filter thread and uniform gear positions for aperture and focus rings make it compatible with a wide range of matte boxes and follow focus systems. The focus ring offers 300 degrees of rotation with fluorescent scales for precise operation in low-light environments.
