What is the sigma 28 45mm f 1 8 dg dn art good for?

The Sigma 28-45mm f/1.8 DG DN Art is a short, fast zoom for full-frame Sony E and L-Mount cameras. Its f/1.8 aperture holds across the whole range, so it's strong in low light and gives real background blur. On full frame it covers wide to standard views, which suits environmental portraits that show where someone is, as in the portraits guide. It's a sensible pick for a standard-range lens, as the lenses guide suggests for a first kit. Keep in mind it isn't stabilised. On APS-C it frames like 42-68mm and gives about the blur of f/2.7, which you can work out with the focal length converter.
