Rank #5 in Best 24-70mm Lens 2026: 9 Ranked, Aperture Claims Checked
Sigma 28-70mm F2.8 DG DN (Sony E)
Price and rating as shown on Amazon when we collected them. Both change.
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.

What buyers actually say
Quoted from customer reviews on Amazon
Verified purchase“It's heavy.Picture quality is amazing. Corners at 24mm are a bit stretched. Some vinyeting. reversable lens hood button is a pain in the ass.”
“I tend to shoot with my 24mm, 35mm or 85mm primes. Over time I have noticed (because I can't be bothered to change lenses) I left my camera in my bag more often than not. Also, I don't like to carry too much with me, so I could never decide what to take.To solve this very first world problem, I bought this lens.Firstly, I really like the size...it's very small and light (about the same size as my Sony 24mm 1.4) which was a big consideration. I had considered the Sigma 24-70mm, but found that too front heavy. The other obvious choice would have been the Tamron 28-75mm. However, this was more expensive and from the reviews I have seen, didn't really warrant the additional expense and weight.Image quality is good. I have tested it against my primes and while it doesn't match those (and I'm sure it isn't as good as Sony's 24-70mm GM), I find the quality to be more than good enough for real world shooting. Without pixel peeping, it's very hard to see any real negatives.The lens does get softer at 70mm, but again, unless you are comparing against a prime or pixel peeping, you won't notice any difference in the real world.Build quality is also good. It's made of high-quality plastics and feels solid in the hand as most Sigma lenses do these days. I really like how Sigma have managed to keep this lens so light without jeopardising the build quality (unlike a company like Samyang, where they feel very cheap).Overall, I'm very pleased with the purchase and it hasn't left my camera since I bought it.”
