Sigma 14-24mm f/2.8 DG DN Art Lens for Sony E

Description Sigma 14-24mm f/2.8 Sigma 14-24mm f/2.8 DG DN Art Lens provides a versatile range of wide-angle focal lengths. With excellent image quality while optimizing size and weight. A Super Multi-Layer Coating combined with a NanoPorous Coating. Also helps to suppress lens flare and ghosting to a greater degree than conventional anti-reflective coatings. This helps to more effectively produce colour-accuracy and contrast-rich imagery in a variety of lighting conditions. Additionally, a built-in lens hood serves to protect the front element as well as prevent stray light from causing flare. It is also suitable for APS-C models where it provides a 21-36mm equivalent focal length range. Five Special Low Dispersion (SLD) elements and one F Low Dispersion (FLD) element markedly reduce chromatic aberrations and colour fringing throughout the zoom range for improved clarity and colour accuracy. Three aspherical elements, including a large-diameter aspherical lens, control spherical aberrations and distortion for increased sharpness and accurate rendering. A Super Multi-Layer Coating combined with a NanoPorous Coating has been applied to lens elements in order to minimize lens flare and ghosting to a greater degree than conventional anti-reflective coatings. The combination of these coatings produces contrast-rich and colour-neutral imagery, and help to make the lens even more effective in backlit conditions. A stepping AF motor benefits both photographers and videographers with its fast, precise, and near-silent performance. Rounded eleven-blade diaphragm contributes to a smooth and pleasing bokeh quality. Weather-resistant construction with a brass bayonet that affords improved mounting accuracy and rigidity.
