40mm T1.9 cinema lens for Sony E

The NiSi Athena Prime 40mm T1.9 is a full-frame cinema lens designed for Sony E-mount cameras. It covers a 46mm imaging circle and delivers a consistent look across the Athena Prime series. Synchronised focus and iris ring positions allow quick lens changes without re-rigging accessories. The wide T1.9 aperture creates shallow depth of field and smooth bokeh for cinematic storytelling.

Check mount and coverage before ordering

Verify that your camera uses a Sony E mount and that its sensor fits within the 46mm image circle. The lens is built for full-frame formats; smaller sensors will crop the field of view. Ensure your matte box or follow-focus system matches the unified ring positions shared across the Athena range. No electronic contacts are mentioned, so aperture and focus remain fully manual.

Unified build with integrated filter holder

The lens shares identical weight and ring placement with other Athena primes, keeping balance consistent on gimbals or shoulder rigs. An integrated filter holder accepts NiSi filters directly, reducing front-end bulk and speeding up filter swaps. Minimised focus breathing maintains a stable angle of view during pulls. Metal construction and precise tolerances support daily production use without play or shift.

Questions about this item

Does the NiSi Athena Prime 40mm T1.9 include a filter holder or must I purchase one separately?

The lens ships with a dedicated filter holder included in the box, so no separate purchase is required for that accessory.

How do I decide between this 40mm focal length and other Athena Prime lenses?

Choose the 40mm when you need a natural perspective close to human vision; its T1.9 aperture and 46mm imaging circle match the rest of the series for consistent operation.

What does the T1.9 rating deliver when the lens is mounted on a full-frame Sony E camera?

T1.9 provides a wide aperture for shallow depth of field and strong low-light performance while maintaining consistent exposure during focus pulls across the 46mm image circle.
