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 colour 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 colour-neutral imagery, even in backlit conditions.

A stepping AF motor benefits both photographers and videographers with its fast, precise, and near-silent performance.

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

The lens is constructed using a Thermally Stable Composite (TSC) material, along with traditional metals, for greater precision and use in wide temperature variations. The outside of the lens barrel is also engraved with the year of production.

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