DxOMark on the Sigma 18-35mm f/1.8 DC HSM A: “best performing APS-C zoom”


DxOmark tested the Sigma 18-35mm f/1.8 DC HSM A lens for Canon mount ($799) and labeled it as the "best performing APS-C zoom":

"With the introduction of this model, Sigma has the best performing zoom of its type. The DxOMark score of 25 points puts well ahead of both the full-frame Canon EF 24-70mm f/2.8 L II USM and the Tamron SP 24-70mm f/2.8 Di VC USD (though bear in mind those lenses become the equivalent to a 38-112mm on a Canon APS-C body)."

Here are few comparisons between the Sigma 18-35mm f/1.8 and other lenses (even some primes):

    that’s just amazing performance…a 1.8 zoom that beat the hell out of BOTH primes and zooms that cost 2~3 times more.

  • Kudos for Sigma – again, since I already said that. From cheapo lenses to very, very high quality – better than L, huh? I don’t know what kind of black magic they are using but keep the great work with these new line ups.

      Yes, yes, and maybe make at least 20% of production actually working and better yet let AF work at least sometimes please …

    Yawn. DXO software it’s not really good, I tried it a while back and it was full of little issues. Those “tests” are even more pointless.
    Result: I leave it to M43 shooters.

    While other tests come to similar conclusions regarding the quality of the new Sigma Zoom, the DxOMark ratings are positively humbug. The DxOMark lens score is calculated so that a fast lens automatically gets a significantly better score, and would have to perform significantly worse in image quality to only reach the score of a slower lens. And that’s not the only thing that shows their test method is severely misguided.

      If you look at dxomark, pentax lenses perform horribly. I know from using them that this is really not the case in real life, so I question their testing methods. Usually photozone is fairly accurate. If you ask me real world samples say a lot more about how a lens performs. I want to see how fine detail like leaves and grass are rendered. So what, do they print an 8×10 and test that or something? I wouldn’t be surprised. Resolution doesn’t even factor into their DSLR tests hardly.

        You are absolutely right about that. They scored all of the Limited lenses from Pentax extremely poorly, and they are beautiful lenses. DXO doens’t take into count things beyond their scientific tests that make a lens good. That’s why the Zeiss 50mm scores so low, where as I prefer it to sharper lenses because of the specific look you get from it at f2. I don’t care who scores high or low, these tests are just navel gazing.

      • madmax

        Agree. Photozone and DSLR magazine are the best webs testing lenses. This said, Sigma quality and price put to shame overpriced competition.

  • Koks

    It’s old and known, many tests confirm that this lens is breakthrough for APS-C format: http://www.lenstip.com/2050-news-Sigma_A_18-35_mm_f_1.8_DC_HSM_-_lens_review.html

    Although it promises to be a great lens, it cries out a for a good 35-70mm APS-C lens to complement this lens. Now if Sigma has such a lens on the drawing board, good for them, as both Nikon and Canon only give APS-C lenses lip-service, and they don’t make a lot of advanced lenses in this format.

  • Zos Xavius

    I was really excited about this lens until I finally looked at some real world samples. This lens has good resolution, no doubt about it, and is reasonably sharp across the whole frame even at its extremes, but clearly the 50D sensor in the pics I saw was out-resolving the lens, so I wouldn’t go so far as calling it a stack of primes. For a sigma lens this is very good and for what it costs it is exceptional. If I didn’t have the very good Pentax 16-45 already, I would be looking at this with slightly more interest. This lens would be a dream for street photography, but its size would hardly allow you to inconspicuous.

    well done sigma… again!

  • Genkakuzai

    Sigma are kicking some serious ass these days, I like it! ^^ Their newish 35mm f/1.4 is still on my list of gear to get.

  • johnny

    It’s time to release newer version of 24-70/2.8 OS HSM & 70-200/2.8 OS HSM. Current Canon’s prices are ridiculously high.
