The Sigma 28mm f/1.4 DG HSM Art Lens for Sony E is a wide-angle prime designed for full-frame mirrorless cameras, offering a balanced field of view suitable for street photography, landscapes, environmental portraits, and documentary work. Its fast f/1.4 maximum aperture enables confident shooting in low-light conditions and precise control over depth of field, allowing subjects to stand out while preserving context. When used on APS-C cameras, the lens provides a 42mm equivalent focal length for a more natural perspective. The optical design incorporates two FLD and three SLD elements to reduce chromatic aberrations and color fringing, along with three aspherical elements that minimize distortion and spherical aberrations. This construction supports high levels of sharpness and consistent image quality across the frame. A Super Multi-Layer Coating reduces ghosting and flare, helping maintain contrast and color accuracy even in challenging lighting. Autofocus is driven by a Hyper Sonic Motor that provides quick, quiet, and accurate performance, supported by an optimized focusing algorithm. Full-time manual focus override allows fine-tuning without interrupting workflow. An electromagnetic aperture mechanism provides stable exposure control, particularly beneficial during high-speed shooting sequences. Built to professional standards, the lens features a brass bayonet mount for rigidity and precise alignment, along with weather-resistant sealing to guard against dust and moisture. A protective front coating repels water and oil, aiding maintenance in outdoor conditions. As part of Sigma’s Art series, this lens emphasizes optical precision, mechanical reliability, and creative flexibility.Bundle Includes:Sigma 28mm f/1.4 DG HSM Art Lens (Sony E)Cleaning KitProfessional MC 3 Piece Filter Kit77mm UV/CPL/FLens Cap Keeper
