Nisi Athena Prime 135mm T2.2 Cinema Lens Sony E

Cinema lens for full-frame Sony E-mount

The NiSi Athena Prime 135mm T2.2 covers a 46mm imaging circle, making it suitable for full-frame sensors on Sony E-mount cinema cameras. Its 135mm focal length provides a narrow field of view ideal for tight portraits, detail shots and compressed perspectives in narrative work. The lens is sold without a drop-in filter holder, keeping the front end clean for matte-box workflows. It is built for filmmakers who need consistent optical performance across the Athena Prime series.

Optical behaviour under sustained use

Advanced micro-contrast control and minimal chromatic aberration preserve sharp detail and lifelike colour throughout long takes. The T2.2 aperture delivers strong subject isolation with a soft, pleasing background rendition that holds up across extended shooting days. Focus breathing is minimised so the field of view remains consistent when racking focus, preventing unwanted shifts in composition during critical scenes. Iris and focus ring positions match the rest of the Athena range for familiar, repeatable operation.

Thermals noise and power draw

As a passive manual cinema lens, it draws no electrical power and produces no fan or motor noise during operation. The all-metal barrel dissipates heat naturally without active cooling, ensuring silent performance on sensitive audio sets. No batteries or external power are required, simplifying rigging and eliminating a point of failure during continuous recording. The mechanical design maintains stable focus and iris positions regardless of ambient temperature changes.
