Sigma Lens 24-70mm F2.8 DG DN Sony E-mount Zoom Standard Full-size Mirrorless Art It's been about a year since I bought it new, and I've only used it a handful of times, so it's in beautiful condition. There are some minor scratches on the caps, etc., so please refrain from purchasing if you are concerned. An outstanding large-aperture standard zoom lens with class-leading performance that delivers overwhelming resolution across the entire zoom range. Taking advantage of the optical design advantages specific to mirrorless cameras, it extensively uses 6 FLD glass elements and 2 SLD glass elements as special low dispersion glass in its glass materials. It also employs 3 aspherical lenses, thoroughly suppressing difficult-to-correct aberrations such as axial chromatic aberration and sagittal coma aberration, achieving uniform and high optical performance from the center to the periphery of the entire zoom range. Various functions can be assigned to the AFL button from the camera body, improving operability during shooting. The adoption of a stepping motor and algorithm also achieves both high-speed AF drive and quietness. Considering shooting in harsh conditions, it adopts a dust- and drip-proof structure and a water- and oil-repellent coating. In addition, it is equipped with various functions such as an AFL button that can assign various functions to the lens barrel, a zoom lock switch that is released by zoom operation, and a comfortable AF/MF switching switch.
