Also the two pro cameras exposed completely different
Canon 1DX exposed much longer compared to Nikon
We are comparing "Canon" ISO and " Nikon" ISO and the results of the test target
wrong, DxOMark is
wrong, and now IR is right, but only if we look at different ISO settings but try to match the other exposure settings, and only if we stop talking about the 1D X and start talking about the 5DIII instead.
...first look after that Canon have been exposed the same time as Nikon, Canon can not have a longer exposure time , and sometimes a whole Stop more and then call it for example 12800iso , when in fact it is 6400iso
You are saying the IR images are differently exposed, but 'we' weren't talking about IR data at all, nor were 'we' talking about the 5DIII - you are the only one doing that. Where are your data showing that DxOMark and William Claff exposed the test images for the 1D X and D800 differently? Or now that you've decided their data no longer support whatever argument it is you're trying to make, we should stop talking about them and start talking about different data on different cameras, is that it? We should also ignore the fact that different lenses set to the same f/stop may very well have different T-stops, which would necessitate different exposure settings. Really hate those inconvenient truths...
so be carefully when ... the parameters are not the same
Let me get this straight. You show Claff data supporting a point, when shown Claff data refuting that point, you show DxOMark data to refute the Claff data. When shown DxOMark data refuting the earlier Claff data, you bring out IR data about different cameras than were being previously discussed
. What's next? Roger Clark data comparing the 40D to the D90?
So if you will discuss high iso reproduction , noise and resolution with me ,first look after that Canon have been exposed the same time as Nikon, Canon can not have a longer exposure time , and sometimes a whole Stop more and then call it for example 12800iso , when in fact it is 6400iso
Your arguments are clearly biased and have become tangential. Discussion with someone displaying an obvious bias is ultimately fruitless, so I'm done discussing anything with you. Have a good night.
