The design suits working in available lighting conditions while affording increased control over depth of field. More lightweight and compact than similar 24-70mm lenses, it's optical design incorporates two FLD and two SLD low-dispersion elements plus three aspherical elements that reduce a variety of aberrations to achieve high sharpness, enhanced clarity, and improved color accuracy. It features just one lightweight focusing element, which keeps the AF unit small. This, along with a quiet and fast stepping motor, makes for responsive and near-silent autofocus performance, an ideal combination for filmmakers looking for a high-performance, lightweight, and easy-to-handle camera system that works well with a gimbal or other accessories.\u003cbr\u003e\u003cbr\u003eEach optical surface features Super Multi-Layer and Nano Porous coatings to improve contrast and color rendering by suppressing lens flare and ghosting for optimal light transmission, and an added water- and oil-repellent coating on the front optic helps keep the lens free from smudges and droplets. The weather-sealed design benefits working in trying environmental conditions, and a nine-blade rounded diaphragm contributes a pleasing bokeh quality when using wider apertures.\u003cbr\u003e\u003cbr\u003eStandard zoom for full-frame E-mount mirrorless cameras\u003cbr\u003e42-105mm equivalent focal length when used on an APS-C camera\u003cbr\u003eConstant f\/2.8 maximum aperture for Low light use and depth-of-field control\u003cbr\u003eTwo F Low Dispersion (FLD) and two Special Low Dispersion (SLD) elements reduce chromatic aberrations and color fringing\u003cbr\u003eThree aspherical elements control spherical aberrations and distortion\u003cbr\u003eBoth Super Multi-Layer and Nano Porous coatings minimize lens flare and ghosting and produce contrast-rich and color-neutral imagery\u003cbr\u003eIntegrated stepping motor and optimized AF algorithm provides quick and quiet autofocus\u003cbr\u003e28mm minimum focus distance: 7.5\", 1:3.3 magnification\u003cbr\u003e70mm minimum focus distance: 15\", 1:4.6 magnification\u003cbr\u003eRounded nine-blade diaphragm for a pleasing bokeh quality\u003cbr\u003eBrass bayonet for mounting accuracy and rigidity\u003cbr\u003eRubber sealing for dust- and splash-resistance","brand":"Sigma","offers":[{"title":"Default Title","offer_id":48283637612759,"sku":"SG2870MMDGDNSE_sses","price":728.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0792\/4003\/6567\/files\/664179.jpg?v=1780498014","url":"https:\/\/ssephotovideo.com\/products\/sigma-28-70mm-f-2-8-dg-dn-contemporary-lens-for-sony-e","provider":"Ssephotovideo","version":"1.0","type":"link"}
