The Sigma 28-70mm F2.8 DG DN is a Sony E-mount zoom covering 28mm to 70mm, listed at £631.39 and rated 4.6 out of 5 from 677 ratings. It takes number 5 in this guide. The listing's own bullets call it lightweight and compact, with internal focusing, a focus mode switch and a nano porous coating, and the rating breakdown is 77 five-star, 15 four-star, 4 three-star and 4 one-star ratings — 4 in every 100 are one-star.

The number that does not hold up on this page is the aperture. The spec table gives the Maximum Aperture as '2.8 Millimetres' — millimetres measure length, not how wide a lens opens — and then gives the Minimum Aperture as 2.8, the same figure it just called the maximum. The same table calls a 28-70mm zoom a 'Telephoto', records a 'Fixed Focal Length' of 70 Millimetres for a lens that zooms, and lists a Screen Size of 72.2 Millimetres for a lens that has no screen. Everything here is taken from the Amazon listing for this product; none of it comes from testing we carried out ourselves.
