And what percentage are not from someone like neuro?
List a specific claim. I don't feel like digging and wasting my time over nonsense.

I said regarding the sub-data on their sensor tests, not their overall sensor scores or anything at all to do with their lens scores.

This is probably true. Canon if you are out there. I will always say good things about you to everyone if you send me a free 1DX or 5DSR.dilbert said:

Re: 5DS scores at DXO drop **tomorrow** (i.e. 7/8/15)
Well... they can have a contrast limit so that's kind of like DR and will have an effect on actual DR.
all that is available, at least in comparative form rather than absolute dimensional numbers, for tested lenses for a given platform. The raw data is very useful.

Which makes no sense if they shoot Canon.
I (overall) really enjoy using my 70D, but I don't make excuses (as a semi-technology enthusiast) it is behind the competition a bit in some sensor aspects.
I stuff up the pictures more than it's weaknesses; but I don't make excuses for where it's sensor is weak.
It takes really nice pictures I like to look at; but I don't make excuses for where it's sensor is weak.
And yes, I will continue to keep giving criticisms rather than make excuses for it like some of the fanboys seem to. DxO is about these technical measurements so if you want to talk about the camera overall, a DxO related thread is NOT the place for it.

On to the actual 5ds/r sensor metrics.
nothing new, no big improvements, same surface area performance we've seen from Canon for a very long time.
The increased pixel density will certainly be of some benefit to those who need it, as it does come with a slight per-pixel improvement at base iso.
The biggest improvement, other than 51MP, is that the thing likely has more usable DR than bodies prior to the 7D2, simply by virtue of significant reductions in fixed pattern noise.
2 yrs ago I decided to use 36 million superior pixels and am glad I did not wait for this.
OTOH, I would not be disappointed with a 5ds if I didn't know what I was missing on the other side of the paddock. ;D
edit: hey, 5ds has per-pixel performance very close to that of my much-liked old 40D!
that's an absolute sensor performance improvement of ~1.33 stops in only 8 years.
Way to go, Canon.

Ohh damn, I wasn’t aware of this immense DxO One camera (no surprises there really), now my saving for that 5D3 has reached a level which means I can buy this new incredible camera immediately, decisions decisions………………….ohh wait, I have a line of existing lenses that fit a 5D3 but not a DxO One! Damn, looks like I’ll need to miss out on that superior camera ;DPureClassA said:

I think about 90% of all posts in this thread that denigrate DxOs figures refer to the (quite clearly ludicrous and biased) score of the DxO One. However, a handful of spurious figures shouldn’t detract from some interesting component scores, and while the methodology may be pseudo-scientific, so long as it is the same methodology between systems (and particularly within manufacturers) then it is useful to compare certain aspects of a sensor. FWIW, and in the limited number of systems I have had lots of experience with, I have found DxO to pretty closely resemble my own take on them. Canon never claimed the 5DS to be a giant stride in all aspects of sensor capture other than resolution, and in this regard it is a success - and this has been reflected by DxO giving it the highest score (for a Canon).

Wow so much hate for DXO Mark.
I have run my own tests Nikon vs Canon as myself and my family own both types of gear, and I can replicate every result that DXO produce.
I even managed to replicate an interesting flaw in their testing, one lens showed better sharpness at f16 than all others, I replicated this and discovered that this lens did not actually stop down to F16 but was still at F11 giving the erroneous result.
I have found them to be extremely reliable, and these new figures they have posted pretty much match exactly what everyone else is saying.
For example, they say that the low light score, ie the ISO performance is behind that of the D810, but very similar to that of a 5DMKIII
DP Review example pics show exactly this.

They say the dynamic range is behind that of the D810, but improved from previous Canon cameras.
DP Review examples show the same thing.

What all these results show is that unlike Sony and Nikon, who have managed the feat of giving you more pixels and better iso and better DR all in the same full frame package, Canon have simply scaled up the 7D MK II's crop sensor with all its compromises. It is not a great leap forward in technology, and the upcoming Sony 42Mpix backlit sensor is probably going to destroy it.
An interesting point, I tested Nikon D810 with 24-70 vs Canon 5DMK II with 24-105 lens, I found that the Nikon at 70mm resolved the same as the Canon at 105mm. As a *system* this is what matters when producing a file. And that is what DXO Mark scores showed this. They also showed that the Nikon 24-70 would suffer CA in the corners, and that is what I found.
So I expect that now there is a system that has 50mpix and some great lenses, you will see Canon lenses up top with some of the best performing sharpness scores, and I think we will see the big white telephotos finally showing just how sharp they are on a sensor that can resolve all they can give.

OTOH, there are people like Sporgon – a photographer with substantial talent (I've seen his website...and I've seen yours) – who bought and used the 36 MP Exmor along side Canon gear for some time. His three word review of Exmor: "I sold it."

Yes, their extremely reliable data show that the 17-40L at f/4 is as sharp in the corners as in the center. Their extremely reliable data showed that the 70-200/2.8L IS was superior to its MkII successor, and when challenged they defended that conclusion...until a year later when they silently updated their data without admitting their mistake.
I do find their measurements generally useful, as long as they are viewed with the understanding that there are glaring errors in some of their data. I find their Scores to be useless and misleading.
