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.Ī 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.Ī stepping AF motor benefits both photographers and videographers with its fast, precise, and near-silent performance. Normal-length prime is designed for APS-C-format Sony E-mount mirrorless cameras and provides a 45mm equivalent focal length.īright f/1.4 maximum aperture excels in low-light conditions and also affords increased control over depth of field for achieving selective focus effects. It gives an effective focal length of 45mm (48mm for Canon), thus giving a standard viewing angle similar to using a 50mm lens on a full-frame camera. Additionally, benefitting both stills shooting and video recording, this compact prime also incorporates a stepping AF motor for smooth, near-silent autofocus performance.Īs 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.
