Sigma has launched a new full-frame standard zoom lens with a constant f/2.8 aperture. But where most f/2.8 standard zooms have a 24-70mm focal length, the new Sigma ups the ante by offering a 28-105mm focal range.
The Sigma 28-105mm F2.8 DG DN | Art has been designed for a wide range of subjects, from landscapes to all forms of portraiture, and even close-up shots, thanks to a 40cm minimum focus distance available throughout the focal range. That large maximum aperture also means low light needn't be an issue, and Sigma is claiming the 12-blade rounded diaphragm produces "beautiful" bokeh.
