A fast, versatile prime, this 30mm f/1.4 DC DN Contemporary Lens from Sigma is designed for APS-C-format Sony E-mount mirrorless cameras, where it provides a 45mm equivalent focal length. The bright f/1.4 maximum aperture benefits working in low-light conditions and also affords extensive control over focus placement for using selective focus techniques. In regard to the optical design, one aspherical element and one double-sided aspherical element pair to significantly reduce spherical aberrations for increased clarity and definition for notably sharp image quality. A high-refractive index element is also featured, to minimize color fringing and chromatic aberrations, and 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 or smooth, near-silent autofocus performance. Designed as a versatile standard lens, the mixture of speed and optical prowess make this a go-to lens for mirrorless shooters.
- A truly versatile standard prime, this 30mm lens is designed for APS-C-format Sony E-mount mirrorless cameras where it provides a 45mm equivalent focal length.
- Fast f/1.4 maximum aperture excels in low-light conditions and also affords greater focus control for producing shallow depth of field effects.
- One aspherical element and one double-sided aspherical element control a range of spherical aberrations and distortions for increased sharpness and resolution. Additionally, a high-refractive index, high-dispersion glass element is also integrated into the design, and offers anomalous partial dispersion characteristics to control chromatic aberrations and reduce color fringing.
- 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.
