DxOMark investigates lenses for Canon EOS 6D, and Sigma 30mm F1.4

By dpreview staff on Jul 19, 2013 at 14:20 GMT

Our friends and collaborators over at DxOMark have been investigating lenses for the Canon EOS 6D, and have tested no fewer than 95 lenses from Canon, Samyang, Sigma, Tamron, Tokina and Zeiss to see which score highest. The results are presented in a multipart article, that also compares the EOS 6D results to those from the EOS 5D Mark III and the Nikon D600. Meanwhile for APS-C SLR users, this week DxOMark also reviewed two fast lenses from Sigma, the 30mm F1.4 DC HSM and (in case you missed it earlier this week) the 18-35mm F1.8 DC HSM.

Well, good show on the testing. This collaboration seems to be working out for them.

thank you dxo. I appreciate this information. Not everyone uses MF so a score for autofocus would have also been appreciated as sharpness is useless without fast, accurate AF.

I sincerely hope the extraordinary amount of dismissive comments that pop up everytime an article involving DxO is published has nothing to do with them being french. Otherwise I'd think of it as a reminiscence of the anti-french feel of the George Dubya era. ('Freedom fries', anyone...?)

Personally, I couldn't care less about DxO's nationality, but I find that DPR's studio and high resolution samples are a much better way of determining a lens/camera's characteristics.

I hate DxOMark. Their website is useless. They probably have some results but getting out is hopeless.

"Our friends and collaborators over at DxOMark have been investigating lenses for the Canon EOS 6D"

They improved their testing speed tremendously about the time you started collaborating. A year ago they barely released an article a month.

I guess extra cash infusion helps. :)

Didn't they do the same thing for 5DM3? How's 6D different than that for lens selection?

Meanwhile many non-Canikon lens are still not tested.

DxO sells a product that claims to corrects for body+lens issues. These published results are just a side product that comes a little additional cost. So I'm shocked, shocked I say, that DxO is testing the combinations that add value to their product over more obscure combinations that are not used often by DxO customers.

The 30mm prime is worse than the 18-35 zoom.

tamron 70-200mm f2.8 as sharp as canon 70-200mm f2.8 II ??? ... what a joke.

i returned the tamron after 5 days.
on the long end the difference is very noticeable without the need for testcharts.

no way it comes close to the latest canon model.. DxO again.. no real world relevance.

I guess I don't understand how DXO formulas and weighting work. They show a better snapshot score for the Nikon 24-85 over the Canon 24-105 but yet the Canon appears to win every category except for light transmission. The Canon edges out on sharpness, is better on distortion, vignetting and CA plus it has a wider zoom range and is constant aperture. Apparently there is one FL and aperture where the Nikon exceeds the Canon so it gets a better overall score? Am I interpreting this correctly?

Because DxO mark tests lenses + bodies. On a 20MP 6D, the 24-105L tops out at "19" while on a 24MP D600 the 24-85 tops out at "22". So yes, if you look at just the headline score, the 24085 is better. If you look at the details, maybe not. That different ways of looking at the data give different results has been true of lens testing since forever. You are taking the numbers too seriously and assigning them too much precision - do you think you would really pick which lens was which in a real world test of resolution at common settings? So you know how subtle and perfect the focus and target have to be to reliably tell the difference between 19 and 22?

Canon lenses failed by their low resolution cameras.

I wish they had a proof reader, it makes the comparisons seem rather hastily put together (comparison nikon and sigma).

They need to get the Fuji X Series in the mix.
