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 the 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 reduces 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.  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. Bright f/1.4 maximum aperture excels in low-light conditions and also affords increased control over the depth of field for achieving selective focus effects. A Super Multi-Layer Coating has been applied to lens elements in order to minimize lens flare and ghosting and contribute to producing contrast-rich and color-neutral imagery, even in backlit conditions. The rounded nine-blade diaphragm contributes to a smooth and pleasing bokeh quality.
