Sigma 24-70mm f/2.8 DG DN Art Lens for Sony E- Mount Mirrorless Cameras

Sigma 24-70mm f/2.8 DG DN

The F2.8 Art zoom flagship zoom lens series is developed primarily to achieve superior optical performance. As extra-low dispersion glass materials, six sheets of “F” low dispersion (FLD) glass and two sheets of special low dispersion (SLD) glass are lavishly employed while taking advantage of an optical design dedicated for mirrorless lenses. By employing three aspheric lenses, this zoom lens thoroughly subdues aberrations such as axial chromatic aberration or sagittal coma aberration, which are difficult to correct in post-processing, tailors the resolution and achieves uniformity and superior optical performance from the center to the periphery throughout the zoom range.
The mirrorless camera-dedicated design successfully contributes to reduction in the lens size and weight.
