NiSi Athena Prime 18mm T2.2 (RF-Mount)

Professional Full-Frame Cinema Performance

The NiSi Athena Prime 18mm T2.2 is a high-performance wide-angle cinema lens designed for the Canon RF-mount system. Engineered for demanding filmmakers, this lens delivers exceptional image quality with a 46mm imaging circle, providing full-frame coverage with minimal distortion and superior edge-to-edge sharpness.

Advanced Optical Engineering

Each lens in the Athena series is crafted with maximum micro-contrast control and ultra-low chromatic aberration. The T2.2 aperture ensures excellent low-light performance and a soft, natural bokeh that creates beautiful background separation for cinematic storytelling. The optical design is specifically optimized to minimize focus breathing, ensuring a consistent field of view during critical focus pulls.

Seamless Production Workflow

The NiSi Athena Prime series is built for efficiency on set. All lenses in the range are matched in weight and dimensions, allowing for rapid lens changes without the need to rebalance gimbals or stabilizers. The standardized 77mm filter thread and consistent gear positions for aperture and focus rings make it compatible with a wide array of follow focus systems and matte boxes.

Precision Control and Versatility

• 300-degree Focus Throw: Features fluorescent focal scales for precise manual focus adjustments in low-light environments.
• Drop-in Filter Mount: Offers a flexible workflow for adding ND or creative filters directly into the rear of the lens.
• RF-Mount Compatibility: Native mount design ensures a secure and stable connection for professional mirrorless cinema cameras.
