Sigma 30mm f/1.4 DC DN Contemporary Overview
Unveiled: Sigma 50-100mm f/1.8 Art & 30mm f/1.4 Ultra-Fast APS-C Lenses & MC-11 Adapter
 
SIGMA 16mm / 30mm / 56mm F1.4 DC DN Contemporary Mirrorless Lens Trio (on full frame cameras, too!)
 
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 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. Additionally, benefitting both stills shooting and video recording, this compact prime also incorporates a stepping AF motor for smooth, near-silent autofocus performance. A rubber sealing at the lens mount helps protect against dust and other elements entering the lens or camera.
 
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.
 
Normal-length prime is designed for APS-C-format Sony E-mount mirrorless cameras and provides a 45mm equivalent focal length.
Bright f/1.4 maximum aperture excels in low-light conditions and also affords increased control over depth of field for achieving selective focus effects.
Two aspherical elements and one high-refractive index element are used to limit distortion and spherical aberrations and also contribute to greater overall sharpness and accurate rendering.
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.
A stepping AF motor benefits both photographers and videographers with its fast, precise, and near-silent performance.
Rounded nine-blade diaphragm contributes to a smooth and pleasing bokeh quality.
Constructed using a Thermally Stable Composite (TSC) material for greater precision and use in wide temperature variations. Additionally, a brass bayonet affords improved mounting accuracy and rigidity.
