Sigma 28-105mm F2.8 DG DN Art review: a not so standard zoom lens

Sigma 28-105mm F2.8 DG DN Art.

Everybody loves a trinity standard zoom, right? With a typical zoom range of 24-70mm, coupled with a relatively fast and constant f/2.8 aperture, they’re great for anything and everything from urban and landscape photography to portraiture and even astrophotography, up to a point. The maximum focal length of 70mm can feel a bit short for portraiture, especially for head-and-shoulders compositions and tight head shots. Tamron stretched things a bit with its Tamron 28-75mm F2.8 Di III RXD, which was also repurposed as the Nikon Z 28-75mm F2.8, before Tamron upped the ante with its subsequent Tamron 28-75mm F2.8 Di III RXD G2 (Generation 2) lens. All three are conveniently compact and lightweight, tipping the scales at a shade over half a kilogram. This Sigma lens goes more properly into telephoto territory, stretching to 105mm instead of 75mm, but is almost twice as heavy. It aims to be among the best lenses for Sony cameras and the best lenses for L-mount cameras.

Even at a focal length of 28mm with no physical extension of the inner barrel, the Sigma dwarfs the relatively compact Sony A7C II camera body, shown here. (Image credit: Matthew Richards)
