Our take on the NiSi Athena Prime 40mm T1.9 Cine Lens

The NiSi Athena Prime 40mm T1.9 is a full-frame cinema prime built for mirrorless mounts, here in Canon RF. It sits between the 35mm and 50mm Athenas, giving a slightly wide normal view that works for dialogue, walk-and-talks and gimbal work. The T1.9 aperture is fast for a cine lens at this size, and the Athena line is known for matched color and gear rings across the set. Reviewers rate its build and image for the money but note it is manual-focus only and heavier than photo primes.

What reviewers say

Owners and reviewers describe the Athena 40mm as a well-built, sharp cine prime with clean color that cuts well with the rest of the set. Most praise its mechanics and value against name-brand cine glass; criticism centers on weight and some breathing.

Yes. It covers full-frame sensors and is sold in Canon RF, Sony E, Nikon Z, Leica L and other mirrorless mounts.
Does it have autofocus?

Will it fit my Canon R5 C?
Yes, the Canon RF version mounts directly on RF bodies. It has no electronic contacts, so aperture and focus are set on the lens.
