A full-frame telephoto zoom for Sony E-mount mirrorless cameras, built to be carried and shot handheld rather than locked to a tripod. Sigma uses one FLD and four SLD elements to keep color fringing down across the range, adds four stops of optical stabilization, and drives focus with a stepping motor that is fast and near silent. On APS-C bodies it behaves like a 150-600mm. It is the lighter, more affordable way into long reach than a fast 100-400mm or a 150-600mm sports zoom, and owners accept the slower f/5-6.3 aperture as the trade-off.

Owners treat it as a strong value long zoom: light enough to carry all day, with stabilization and autofocus that hold up handheld. Most criticism centers on the slow aperture and slight softness at the long end wide open.
The Sigma 100-400mm F5-6.3 DG DN OS Contemporary is a telephoto zoom lens for Sony E-mount mirrorless cameras. It is designed for full-frame models. On APS-C models it gives a 150-600mm equivalent focal length range. It belongs to the Contemporary line in Sigma's Global Vision series and has a compact, lightweight build.
The optics include one F Low Dispersion (FLD) element and four Special Low Dispersion (SLD) elements. These reduce chromatic aberrations and color fringing throughout the zoom range. A rounded 9-blade diaphragm contributes to the bokeh quality. Optical image stabilization compensates for up to four stops of camera shake for handheld shooting.
An integrated stepping motor drives fast, near silent autofocus, with an optimized AF algorithm for smoother focusing. The lens has a programmable AFL button, a focus limiter switch and a zoom lock switch that keeps the barrel from extending accidentally. The brass bayonet mount has rubber sealing for dust and splash resistance. The optional TS-111 Tripod Socket attaches for tripod or monopod use. The included PT-31 Protective Cover can be fitted when the socket is not used.
