The NiSi ATHENA PRIME 35mm T1.9 Full-Frame Lens for E Mount is a cinema prime designed for professional video production on Sony full-frame cameras. It delivers sharp center performance wide open at T1.9 with controlled chromatic aberration and smooth bokeh from 10 aperture blades.
Key Specifications
This lens offers a T1.9 to T22 aperture range, 300° focus ring rotation, and 0.8 MOD gears for follow-focus compatibility. It features an 80mm front diameter, 77mm filter thread, 55.1° horizontal angle of view, and 11.8-inch minimum focus distance with minimal breathing.
Optical Performance
Center sharpness excels even at T1.9, improving when stopped down, though edges show some chroma up to T5.6. Micro-contrast control enhances detail without distortion, covering a 46mm full-frame image circle.
Build and Handling
The matte black metal body ensures durability and light control, with consistent mechanics across the ATHENA series for matched sets. Fluorescent dual-scale markings (feet/meters) aid precise use in low light.
