Advanced optics and AF system
In SIGMA 70mm F2.8 AR, 6 elements were used with special low-dispersion glasses SLD and FLD as well as aspherical ones, responsible for increasing the image efficiency at the edges of the frame and close focusing distances. This system of lens and lens construction offers a new level of sharpness and color.The new autofocus drive system is powered by an electric DC motor. The Focus system has no direct mechanical connection between the focus ring and other mechanisms. Thanks to such a solution, the whole system works with the appropriate speed and precision so important in macro photography. In addition, we can manually adjust the focus without having to switch the lens or camera into MF mode.
Compatible with Sony E and converters
SIGMA 70mm F2.8 DG ART lens is compatible with Sony cameras with E mount. There is no need to use the MC-11 converter. The lens is compatible with many additional camera functions, including correction of aberration, continuous AF or matrix image stabilization . So this is the eighth Sigma lens, after the seven lenses shown, which will work with the mirrorless Sony system.The lens also has software compatible with the image correction system implemented in Canon cameras. Thanks to the liquidation of possible aberrations, the vignetting takes place at the moment of taking the picture. In addition, the lens offers the possibility of cooperation with SIGMA 1.4 and 2.0 converters . After connecting the converter 1.4, we get a focal length of 98mm and an F4 aperture, while the AF operation is preserved. After connecting the converter 2.0 we get a focal length of 140mm and an aperture F5.6, in this case the set offers work in the MF mode. However, the solution does not work when mounting Sony E.
