30mm f/1.4 DC DN Contemporary - Sony E Fit

This Sigma 30mm f/1.4 DC DN Contemporary lens is a fast, compact prime designed for APS-C-format Sony E-mount mirrorless cameras, providing a 45mm equivalent focal length suitable for general-purpose photography. The f/1.4 maximum aperture enables strong performance in low-light conditions and provides extensive control over depth of field for selective focus techniques. The optical design incorporates two aspherical elements and one high-refractive index element to minimize distortion and spherical aberrations, while a Super Multi-Layer Coating reduces lens flare and ghosting for improved contrast and color accuracy.

The lens features a stepping autofocus motor that delivers smooth, near-silent focusing performance for both photography and video work, and a rounded nine-blade diaphragm that contributes to pleasing bokeh quality. Constructed with thermally stable composite materials and a brass bayonet mount, this lens balances optical performance with a lightweight, compact design and includes rubber sealing at the mount to protect against dust and environmental contamination.
