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
