Sigma 30mm f/1.4 DC DN Lens

Sigma 30mm f/1.4 DC DN Contemporary Lens is a fast, versatile prime, designed for APS-C-format Sony E-mount mirrorless cameras, where it provides a 45mm equivalent focal length. The Micro Four Thirds version offers a 60mm equivalent focal length. The brilliant f/1.4 maximum aperture is an advantage while shooting in low-light conditions and also affords considerable control over focus placement for using selective focus styles. The optical design, is made up of one aspherical element and singe double-sided aspherical element combined to significantly diminish spherical aberrations for enhanced clarity and definition for remarkably sharp image advantage. A high-refractive index element is also included, to cut down on color fringing and chromatic aberrations, while a Super Multi-Layer Coating has been added to control lens flare along with ghosting in strong lighting environments. In addition, as an advantage for both stills photos and video recording, this compact prime also includes a stepping AF motor for smooth, near-stealth autofocus performance. Created as an all-around standard lens, the mixture of speed and optical adaptability make this a go-to lens for mirrorless shooters.

Truly an all-around slightly-longer-than-normal prime, this 30mm lens is designed for both Micro Four Thirds mirrorless cameras where it provides a 60mm equivalent focal length. and Sony where it delivers a 45mm equivalent focal extent

Fast f/1.4 maximum aperture shines in low-light situations and also provides greater focus control for creating shallow depth of field effects.

A single aspherical element along with adouble-sided aspherical element ruile an array of spherical aberrations and distortions for enhanced sharpness and resolution. In addition, a high-refractive index, high-dispersion glass element is also built into the design, and provides anomalous partial dispersion characteristics to handle chromatic aberrations and diminish color fringing.

A Super Multi-Layer Coating has been added to lens elements as a way to diminish lens flare and ghosting and add to producing contrast-rich and color-neutral images even in backlit situations.

A stepping AF motor is an advantage to both photographers and videographers with its quick, precise, and near-stealth-silent performance.

A rounded nine-blade diaphragm adds to a pleasing bokeh quality.

The lens is engineered using a Thermally Stable Composite (TSC) material, besides traditional metals, for enhanced precision and use in wide array of temperature variations. The year of production is also engraved on the outside of the lens barrel.

The bayonet mount is constructed from brass for ensured accuracy and durability.
