Sigma DG OS HSM lens for Nikon standard Art 24-70mm F2.8 F-mount, zoom, full-frame DSLR, series.

By incorporating three SLD glass elements and four aspherical lenses, various aberrations are corrected. In particular, coma aberration, which degrades point image reproduction, and chromatic aberration, which does not improve even when stopped down, are effectively corrected, resulting in high image quality even at the edges of the screen. By using an aspherical lens with a large ratio of thickness between the center and the periphery, which makes it extremely difficult to mold, high resolution is achieved. The super multi-layer coating reduces flare and ghosting, and enables high-contrast images even when shooting against the light. Nikon F-mount 24-70mm F2.8 Zoom Standard DSLR Full-frame
