Sigma 100-400mm f/5-6.3 DG DN OS Contemporary Lens (Sony E)

The Sigma 100-400mm f/5-6.3 DG DN OS Contemporary Lens (Sony E) is a flexible telephoto zoom that combines a hand-holdable build with apt optical performance. A series of low dispersion glass elements are used to deliver high resolution and sharpness as well as enhanced colour accuracy and reduced chromatic aberrations and colour fringing throughout the zoom range. Optical performance is complemented by intuitive handling, which incorporates a stepping motor that affords quick, quiet autofocus performance along with manual focus control that is refined by an AF/MF switch. Furthermore, four stop-effective optical image stabilisation minimises the apparent effects of camera shake to benefit shooting handheld. The 100-400mm is also compatible with the optional TS-111 Tripod Socket for steadier use atop a tripod or monopod with the Sigma 100-400mm f/5-6.3 DG DN OS Contemporary Lens (Sony E).

As part of the Contemporary line within Sigma's Global Vision series, this lens is designed to achieve a balance between convenience and performance, and meshes a compact, lightweight build and versatile handling with notable optical attributes:

• Telephoto zoom is designed for full-frame Sony E-mount mirrorless cameras but can also work with APS-C models where it provides a 150-600mm equivalent focal length range.
• One F Low Dispersion (FLD) element and four Special Low Dispersion (SLD) elements markedly reduce chromatic aberrations and color fringing throughout the zoom range for improved clarity and color accuracy.
• Optical image stabilization compensates for up to four stops of camera shake to help realize sharp imagery when shooting handheld with slower shutter speeds.

• Integrated stepping motor realizes quick and quiet autofocus, which is further complemented by an optimized AF algorithm to produce smoother focusing performance.
• At the 100mm end of the zoom range, a minimum focusing distance of 3.7' is available, and at the 400mm end, the minimum focusing distance is 5.2' with a maximum magnification of 1:4.1.
• Rounded 9-blade diaphragm contributes to a pleasing bokeh quality.

• Integrated AFL button can be programmed to adjust various shooting settings and the lens also features a focus limiter switch for faster focusing performance within certain distance ranges. There is a zoom lock switch to prevent the barrel from accidentally extending.
• Brass bayonet affords improved mounting accuracy and rigidity, and rubber sealing is incorporated in the mount's design to render it dust- and splash-resistant.
• Compatible with optional TS-111 Tripod Socket for working atop a tripod or monopod; the included PT-31 Protective Cover can be attached to the lens to maintain a seamless appearance if the tripod socket is not used.
