While ensuring the high-definition depiction expected from a large-diameter zoom lens, it also achieves a high standard of two generally contradictory elements: a size that makes it easy to carry around. Polycarbonate "TSC (Thermally Stable Composite)", which has a heat shrinkage rate close to that of aluminum, is used as the material in appropriate places. From the 24-70mm F2.8 DG DN | Art, we succeeded in significantly downsizing the lens body by narrowing the zoom range on the wide-angle side. Although the number of lenses has been reduced, axial chromatic aberration and sagittal coma aberration, which cannot be corrected by the camera's own functions, are thoroughly corrected by using optical design technology as a base and plenty of special glass materials such as 3 aspherical lenses, 2 FLDs, and 2 SLDs. You can enjoy uniform and sharp depiction from the center of the screen to the periphery. Sony E-mount 28-70mm F2.8 zoom standard mirrorless full size
