Sigma SIGMA Sigma L Mount Lens 28-70mm F2.8 DG DN Zoom Standard Full Size Contemporary Mirrorless Exclusive

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, the use of special glass materials such as 3 aspherical lenses, 2 FLDs, and 2 SLDs based on optical design technology thoroughly eliminates axial chromatic aberration and sagittal coma aberration that cannot be corrected by camera-side functions. Corrected accordingly. You can enjoy uniform and sharp depiction from the center of the screen to the periphery. L mount 28-70mm F2.8 zoom standard mirrorless full size
