A fast, versatile prime, this 30mm f/1.4 DC DN Contemporary Lens from Sigma is designed for use with APS-C-format Sony E-mount mirrorless cameras. The bright f/1.4 maximum aperture benefits working in low-light conditions and also affords extensive control over depth of field for using selective focus techniques. The optical design features a pair of aspherical elements, along with one high-refractive index element, which significantly reduce spherical aberrations and distortion for increased clarity and definition for notably sharp image quality. Also, a Super Multi-Layer Coating has been applied to control lens flare and ghosting in strong lighting conditions. Additionally, benefitting both stills shooting and video recording, this compact prime also incorporates a stepping AF motor for smooth, near-silent autofocus performance.
As part of the Contemporary line within Sigma's Global Vision series, this lens is designed to achieve a balance between convenience and performance, and meshes a compact, lightweight build and versatile handling with notable optical attributes.
