  • Full-frame coverage with 46mm imaging circle

40mm T1.9 Cine Lens for Sony E

The NiSi Athena Prime 40mm T1.9 is a full-frame cinema lens built for Sony E-mount cameras. It covers a 46mm imaging circle, making it suitable for full-frame and larger sensor formats. The lens matches the weight and ring positions of the wider Athena Prime series for consistent handling on set.

Suited for narrative filmmakers needing matched

This lens serves directors of photography who require a 40mm focal length with T1.9 speed and minimal focus breathing. It is not for shooters who need autofocus, electronic aperture control, or a zoom range. Buyers wanting built-in filter threads or a wider maximum aperture should look elsewhere.

T1.9 aperture and 46mm circle deliver shallow depth

The T1.9 stop provides strong low-light capability and pronounced background separation. The 46mm image circle gives full-frame coverage with room for sensor stabilisation movement. Focus breathing is minimised to hold framing during rack pulls, though extreme close-focus work will still show slight field-of-view shift.
