Digital Camera World Verdict

If you're looking for a lightweight, affordable alternative to the standard 24-70mm f/2.8, the Sigma 28-70mm f/2.8 DG DN | C ticks all the boxes. It's not quite as wide at the wide end, but if you can get by without that extra 4mm the Sigma is an impressive bit of kit considering the price. The lens feels well built, the focus and zoom rings are smooth, and you can rotate from 28-70mm in one fell swoop. The one downside is that it's not fully weather-sealed, so we wouldn't recommend using it in pouring rain.

For many photographers, a 24-70mm lens is an essential bit of kit, but an f/2.8 variant often comes with a hefty price tag. Even the Sigma 24-70mm f/2.8 Art lens, which is a lot cheaper than the Sony G Master, is still well over a grand. The release of the Sigma 28-70mm f/2.8 DG DN suddenly made this sought-after zoom range so much more affordable. 

Not only does it cost a lot less than the best standard zoom lenses, but it's much smaller and lighter, too, making it ideal for traveling.
