The NiSi ATHENA PRIME 35mm T1.9 Full-Frame Lens with L Mount is a cinema prime designed for professional video production on full-frame cameras like those from Leica, Panasonic, or Sigma. It offers a fast T1.9 maximum aperture for excellent low-light performance and shallow depth of field, paired with 10 rounded aperture blades for smooth, circular bokeh.
Key Features
This lens provides a 55.1° horizontal angle of view, minimal focus breathing, and a 300° focus ring rotation for precise manual control. Fluorescent markings in both feet and meters ensure usability in low light, while the 0.8 MOD gears support follow-focus systems.
Optical Performance
It delivers micro-contrast, low chromatic aberration, and sharp center performance even wide open at T1.9, improving further when stopped down. The 46mm image circle covers full-frame sensors effectively, with an 11.8-inch minimum focus distance.
Build and Compatibility
Weighing around 794g, the lens features an 80mm front diameter for matte box use and includes a drop-in rear filter mount (on mirrorless versions like L Mount). Constructed from aluminum alloy, it matches well with other ATHENA primes for consistent rigging.
Ideal Applications
Suited for narrative filmmaking, documentaries, and low-light shoots, it excels in rigs or gimbals due to its balanced design and industry-standard mechanics
