Tested: Sigma 24-70mm f/2.8 vs Tamron 28-75mm f/2.8

I have both the Sigma and Tamron lenses, and they're both very good

samples, so I decided to do a test. I know people wonder about these

two lenses and new questions pop up from time to time, so hopefully

this will be somewhat helpful.

Excellent review. Perhaps the first I've seen with an objective AF noise comparison.

Thanks!

 

The only suggestion I would make would be to arrange the layout so that the 100% crops are arranged side by side for the lenses at comparable apertures. That would make it a little more easy to compare the lenses, saving the trouble of having to scroll up and down repeatedly.

Thanks for the effort. I have added this to my comparison links.

 

Happy shooting,

Well done Nam Keun Yoon.

And I agree with what Sheldon had to say. :o)

great review

 

Just wondering, is this sigma 24-70 that you've tested the new MACRO version? I heard that this new version that Sigma has is better than the older version.

Nice work here. It's a helpful contribution to the on-going discussion between two excellent lenses. There is copy-to-copy variation for both lenses, however, and I know that my copies of the Sigma were as good or better than my Tamron copies at the long end, so again, this is a copy-dependant issue. Overall they are both excellent lenses, though I would say the build, AF speed, and 24mm wide are significant perks that the EX gives you. Again, nice job.

Hi,

 

Thanks for the comments. I made the changes for the side-by-side comparisons. They're at the end of the crops, in their own links (since the pictures are rather large).

 

Also, if you note the title, the Sigma is the newer Macro version.

 

Jojo: your pictures with your old 24-70mm Sigma was the reason I decided to try it out in the first place. I think I'll stick with the Tamron though, just because it is lighter and quieter, and I don't really need the 24mm. Both of these lenses are so sharp, that decisions as to which lens to keep doesn't come down to sharpness. Any differences seem insignificant.
