The Sigma 28-70mm F2.8 DG DN Contemporary is aimed at photographers who want a 2.8 zoom lens that is both light and compact. The lens is designed for Sony E-mount and L-mount, and it weighs just 470g with a 67mm filter thread. However, the build quality is compromised with a mostly polycarbonate construction, and it lacks weather sealing on the body, although the mount itself is weather sealed. The lens features a manual focus ring and an AF/MF switch, but it does not include optical image stabilization. The autofocus speed is quick and silent, making it suitable for family and travel photography. However, it suffers from noticeable distortion at both ends of the focal length range. The bokeh is generally good, but there is some cat's eye effect in the corners, and the lens exhibits chromatic aberration at times. The sharpness is acceptable in the center, but the corners can be soft, especially at 70mm and wide open at 2.8. Overall, the Sigma 28-70mm F2.8 DG DN Contemporary is a compact option for those who prioritize size and weight, although it has some optical drawbacks.
