NiSi 14mm ATHENA PRIME Full Frame Cinema Lens T2.4 (RF Mount)

The NiSi 14mm ATHENA PRIME T2.4 in RF mount brings the same ultra-wide cinema prime to Canon RF-mount cinema and mirrorless bodies, aimed at filmmakers who want cinema-grade optics matched natively to their camera system. Its T2.4 maximum aperture produces soft background separation at a focal length most zooms can't match for wide establishing shots, and a rear filter mount keeps ND and polarizer filters out of the way of the front element. It shares its size, weight, and gearing with the rest of the ATHENA PRIME series, so it drops into an existing RF-mount cine kit without any rebalancing.

• Fast T2.4 aperture: Delivers soft bokeh and strong background separation at an ultra-wide 14mm focal length.
• Rear filter mount: Accepts ND filters, polarizers, and other filters behind the lens rather than in front, for faster swaps and less risk of front-element damage.
• Minimal focus breathing: Field of view stays consistent from minimum focus distance to infinity, for clean, predictable focus pulls.
• Matched series design: Shares consistent weight, size, and gear position with the rest of the ATHENA PRIME lineup, so switching lenses doesn't require rebalancing a gimbal.
• Precise focus control: A 300° focus ring rotation with fluorescent focal scales supports accurate, repeatable focus pulls in low light.
• Native RF mount: Built for Canon RF-mount cinema and mirrorless cameras, matching the mount and gearing of the rest of the ATHENA PRIME set.
