DxOMark’s Optical Metric Scores Show Different Results: Canon is King

Yesterday, we discovered that DxOMark rated Canon glass according to their own test results to be a bit mediocre. After looking through the results a bit closer, we have to say that we were both right and wrong. If you click on their Optical Metric score system, which simulates a more industry standard test (such as IMATest–a format that I still don’t always believe is ultimately accurate) you’ll see that Canon takes the cake a couple of times.

While Nikon, Samyang, and Sigma still hold their own, Zeiss and Sony start to fall back a bit more on the list. What’s even more amazing is that zoom lenses are more prominent on this list as well with Canon’s 70-200mm f2.8 L USM IS II and Nikon’s 70-200mm f4 G ED VR. At the top of the list is Canon’s 300mm f2.8 L IS USM II–which is a lens that most of us can’t afford. But then Nikon’s new 85mm f1.8 G (which we reviewed quite positively) also stays on top while their new 28mm f1.8 also starts to creep in. Plus the Samyang 14mm f2.8 comes in (we’ve reviewed the Rokinon version) and so does Sigma’s very excellent 85mm f1.4.

These results are  a bit more interesting and can provide much more weight to Canon’s still conservative way of thinking. Overall though, in personal conversations, we as a staff still believe that the company needs to innovate more. In personal real world tests, I actually believe that Nikon’s 70-200mm f2.8 G ED VR II was much sharper than Canon’s option. But this lab test says otherwise.

    Well, not exactly. For reasons that DXO will not answer (see multiple comments on forums) they have not tested the Nikon 300 f/2.8, the 14-24 f/2.8 or even the newer version of the 70-200 f/2/8. So while the old version Nikon 70-200 f/2.8 and the new f/4 both beat the Canon and the 85 1.4g and 1.8g beat the Canon versions at 85 prime, we dont have apples to apples comparisons of many others. Plus, with the heavy sales of the D800, the tests are comparing the D3X with lens against the 5D MkIII and again we don’t know why they have not released tests with the D800 – especially given their premier ranking for its sensor!

    P.S. I’d also love DXO to test the IQ loss with each of the three TC’s and with and without UV filter or polarizer (by brand).

    They haven’t even used a 5D Mk III, only Mk II, they did at least use 3
    1Ds’, but still they should test each lens with the appropriate camera
    for each company to not have people think otherwise of image quality due
    to camera’s focusing systems and such. The camera’s they use also have
    different MP values to compare what is being put through a Lens like
    that really isn’t the way to go.

    So, Canon USA urged/paid you to change your tune? We’ll be taking your reviews with a mighty grain of salt from now on…

      God, you’re an idiot. I really don’t come out and say this that often, but wow.

        Way to encourage dialogue on your site. No matter how misguided the comment, this kind of name-calling is inappropriate from an ‘editor in chief’. Try to be more professional.
