This test is JPG.
Then either Nikon has a really crappy in camera JPG engine to lose a 2.7 stop advantage, or more likely DxOMark scores are not accurate for Canon cameras.
DxOMark uses their own RAW decoder. It is my belief that DxOMark's RAW decoder cannot fully decode Canon CR2 files, so DxOMark scores are not accurate for Canon cameras.
The other possibility is that DxOMark is just marketing shill for Nikon.
Speculation...I've speculated for some time now that dxo could (as a very small company) be influenced (if you know what i mean) to purposely set up their testing procedure to favor one company over another in exchange for.....
Both nikon and canon are large global corporations with significant resources...this "influencing" could easily be done...imo. Again, I'm speculating here, but we've observed time and time again in the global corporate world and in politics all over the world - money influences decisions. Example, in the news today in the US...mitt romney raises $100 million dollars for his presidential campaign...um, that was just for the month of july AND why do citizens and corps give him that kind of money, we know why right?? Also, a couple months ago walmart was accused of a large scale bribary campaign in Mexico....humm.
Just some stuff to think about....and again, im just speculating and providing raw opinion. Thanks.
I haven't seen A SINGLE evidence Canon doing better or even the same in DR department no matter the RAW converter.
DxO has clear methodics, while maybe not covering all the aspects, still being a scientific approach and very usable for one knowing what to do with that info.
Opposite to the forum - one "thinks" and "believes", with absolutely no evidence.
P.S. more than sure, the next gen Canon will have a lot of DR, definitely more than Nikon today.
P.P.S Now this is what I believe - Canon just wanted to use the same old tech for economics reasons. This is why there is no high MP camera currently from Canon - stuffing more pixels in and being less attractive in IQ and asking a premium do not exactly fit together. They compete with versatility, which is quite an argument too. Absolutely fine with that, becuse for most applications the IQ is already so good that it does very well even not being the top notch.
