NiSi Athena Prime 40mm T1.9 (L-Mount)

Professional Full-Frame Cinema Performance

The NiSi Athena Prime 40mm T1.9 is a high-performance cinema lens designed for L-Mount camera systems. Offering a unique focal length that sits between a wide-angle and a standard lens, it provides a natural perspective ideal for narrative filmmaking and commercial production. With a 46mm imaging circle, this lens provides full-frame coverage with exceptional edge-to-edge sharpness and minimal distortion.

Superior Optical Design

Engineered for maximum micro-contrast control and ultra-low chromatic aberration, the Athena Prime series ensures finer image details and unparalleled clarity. The fast T1.9 aperture allows for excellent low-light performance and a shallow depth of field, producing soft, cinematic bokeh for beautiful subject separation and background aesthetics.
