The Sigma 100-400mm F5-6.3 DG DN OS Contemporary lens is Sigma’s first full-frame mirrorless telephoto zoom lens. Designed from the ground up for mirrorless camera systems. Sigma has a new optical formula that ensures edge-to-edge sharpness and high-contrast image quality throughout its entire focal range.
The lens construction is made up of 16 groups and 22 elements, with one FLD and four SLDs used for the effective correction of aberrations and distortions. Its compact size makes it an excellent companion lens to the previously released full-frame mirrorless zooms from Sigma, the 14-24mm F2.8 DG DN Art, and 24-70mm F2.8 DG DN Art. It will be available in Sony E-mount and L-mount.
The fifth Sigma lens designed specifically for full-frame mirrorless camera systems, the 100-400mm F5-6.3 DG DN OS Contemporary has a stepping motor system that is optimized for both phase-detection AF and contrast AF.
The Sigma 100-400mm F5-6.3 DG DN OS Contemporary will be available on July 10, 2020 for $949.00 USD.

It functions as a 140-560mm F7-9 AF ultra-telephoto lens with the Sigma Teleconverter TC-1411, and as a 200-800mm F10-12.6 AF ultra-telephoto lens with the Sigma Teleconverter TC-2011.
