Sigma 18-50mm f/2.8 DC DN Contemporary Lens for Sony E (APS-C, 27-75mm equiv.) - 7PC Accessory Bundle

Compact standard zoom built for APS-C Sony E-mount bodies, covering an equivalent focal length of 27-75mm. The lens offers a constant f/2.8 aperture for reliable low-light performance and precise control over shallow depth-of-field effects. Optical construction includes three high-precision glass-molded aspherical elements to reduce distortion and spherical aberration, plus a Special Low Dispersion (SLD) element to minimize chromatic aberration and color fringing. Sigma’s Super Multi-Layer Coating helps suppress flare and ghosting for better contrast and accurate color rendition in strong lighting. In-camera aberration correction further addresses residual distortion and vignetting. AF is driven by a stepping motor that operates nearly silently, making the lens well suited to quiet shooting situations, video work, and tracking moving subjects. Close-up capability is supported by a minimum focusing distance of 4.8" and a maximum magnification ratio of 1:2.8. A rounded seven-blade diaphragm enhances out-of-focus rendering for pleasing bokeh.
