The Sigma 100-400mm F5-6.3 DG DN OS has been exclusively designed for mirrorless systems, specifically the Sony E-Mount and the L-Mount. Sigma states, “With the optics design specifically for a camera with a short flange back distance, the DG DN series of lenses achieve a supreme combination of optical performance and compactness that could not have been possible with lenses for single-lens reflex cameras ”

The lens comes with a stepping motor optimized for both contrast-detection & phase-detection. The lens construction consists of 16 groups and 22 lens elements, with one FLD and four SLDs used for the effective correction of aberrations and distortions.
