In addition, Sigma’s anti-ghosting and anti-flare coating technology is utilised to boost performance when subjects are backlit, and there are water and oil repellant coatings on the front element to make it easier to clean.įurther good news is that the Sigma 35mm F1.4 DG DN Art is weather-sealed.Īutofocusing is handled by a stepping motor which drives a single, lightweight element, helping to make the autofocusing fast and quiet. This is adjusted using an aperture ring which can be used with or without clicks at the flick of a switch.

There’s also an 11-blade iris which is rounded to help deliver smooth, circular bokeh. Meanwhile the two aspherical elements reduce distortion and maintain image quality across the image frame.

It, plus the SLD and ELD elements, reduces chromatic aberrations. The FLD element is made from glass that has an optical performance close to that of fluorite at a fraction of the cost and weight. Amongst these elements there are two Special Low Dispersion (SLD) elements, an Extraordinary Low Dispersion (ELD) element, an ‘F’ Low Dispersion (FLD) element and two aspherical elements. While the 35mm F1.4 DG HSM Art is constructed from 13 elements in 11 groups, the new Sigma 35mm F1.4 DG DN Art has 15 elements arranged in 11 groups.
