"Features

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.
