A Comparison of the Sigma 24-70mm f/2.8 DG DN Art and Tamron 28-75mm f/2.8 Di III RXD Lenses

A 24-70mm f/2.8 lens is the workhorse of choice for a wide variety of photographers and videographers, and nowadays, there a ton of options out there, many at affordable prices. If you are looking for such a lens, this great video compares the Sigma 24-70mm f/2.8 DG DN Art to the Tamron 28-75mm f/2.8 Di III RXD lens.

Coming to you from The Hybrid Shooter, this excellent video compares the Sigma 24-70mm f/2.8 DG DN Art to the Tamron 28-75mm f/2.8 Di III RXD. Both of these lenses are fantastic options that significantly undercut first-party prices (the Tamron is one of my favorite lenses). One important thing to consider is the focal length difference. While on the long end, you are very unlikely to notice the difference between 70mm and 75mm, the gap between 24mm and 28mm is more significant and may make a difference in your work. That being said, the Tamron is both more compact and cheaper than the already affordable Sigma, so if the focal length difference does not bother you, you may end up preferring the Tamron. Nonetheless, both are great lenses that should satisfy the needs of a wide range of creatives; check out the video for the full rundown between the two.

There is no significant differences between Sigma and Tamron lens! But some features and setting of these two lens have some differences, but It would not be a cause of any big differences.

Did he get money to talk good about Sigma?
have that extra 5mm from 70 to 75 is great for a portrait and he think not that is a big deal .. lol!
The sigma lens is big and bulky, more expensive rings and so on.

He must have done something really wrong with the 75mm test.. looks so unsharp on purpose.
Yes i bias because I have the lens and i know what I get. :)

A little misleading comparing the lenses on a 24mpx sensor. The Sigma is sharper on a higher megapixel body. Both are fantastic for the price and the Tamron is very nice and small. But the Sigma beats the Tamron in sharpness, especially in the 50mm-70mm range.

As an owner of the Tamron with an A7iii, I can honestly say I think the lens is outstanding value for money. I've had several primes, and the only prime I've found to be sharper than the tamron is the 135mm GM. My only gripe with the tamron is the lack of 24mm on the wide end - but I appreciate the weight and cost saving by not having that so it's understandable.

I’ve owned both paired with the A7iii, and ended up selling the Tamron. The Sigma OOF transitions and bokeh are so much better and less nervous than the Tamron. The reviewer should have included some point light sources for the bokeh tests, and then the differences would have become quite apparent.

I personally did not notice a significant difference in sharpness between the two lenses. Regarding AF, the Tamron seems better at eye AF, but the Sigma is much better at focusing macro subjects. Vignetting is far worse wide open on the Tamron. Overall, the differences add up to be significant and I personally am glad to have made the switch. Unless weight is your most important factor, overall the Sigma is just better.
