Cinema lens for full-frame PL cameras
The NiSi Athena Prime 35mm T1.9 is a full-frame cinema lens with a PL mount. Its T1.9 aperture and soft bokeh deliver strong background separation for narrative filmmaking. The lens is built to minimise focus breathing, keeping the field of view consistent during focus pulls. Maximum micro-contrast control and ultra-low chromatic aberration preserve fine detail across the frame.
Check your mount and filter workflow
Verify that your camera body accepts a native PL mount or that you have a compatible adapter with the correct flange distance. The rear filter mount takes rear-mounted ND filters or polarizers, so confirm filter dimensions and thread type before ordering. Because the lens is manual focus and manual iris, ensure your follow-focus system and matte box accommodate the gear rings. No electronic contacts are present, so metadata will not pass to the camera.
Replaces front-filter primes without rear filtration
This lens upgrades from full-frame cinema primes that lack a rear filter mount, eliminating the need for large front filters or matte-box trays. The jump is worth it when you need faster filter changes on set or want to protect the front element from damage. It does not serve shooters who require autofocus, electronic aperture control or lens metadata for post-production workflows.

Questions about this item
Does the lens include rear filters or must ND and polariser filters be purchased separately?
The Athena Prime 35mm T1.9 has a built-in rear filter mount so ND, polariser or other filters can be inserted directly; filters themselves are not supplied and must be bought separately.
Is the T1.9 aperture the only speed option in the Athena Prime 35mm line?
The product data lists a single 35mm focal length at T1.9; no alternative maximum-aperture versions are mentioned for this model.
How does the T1.9 aperture affect exposure and depth of field on a full-frame cinema camera?
At T1.9 the lens transmits the same light as an f/1.9 stills lens, giving very shallow depth of field and strong low-light performance on full-frame sensors.
