Expeed at work here again. Remember these are jpegs.Those are jpegs. Probably Nikon chose a stronger NR for the standard setting of the D7200. According to Bill the difference is about 2/3 of a stop:Yes very strange i see it too!Anyone use the comparometer to look at the D7200 vs D610... I think my tired eyes are playing tricks on me. It looks like the D7200 has lower noise at 12800. Maybe I'm going crazy, or clicked the wrong picture. Need more coffee...
The D610 is still Expeed 3 while the D7200 is Expeed 4.
Expeed 3 cameras seem to use an older basic "Faster" NR while the Expeed 4 cameras use Nikons latest (and more processor intensive) "Better quality NR 2013". At least this is what I am seeing when I open the RAW files in Capture NX-D which shows the in-camera settings. the D5300, D5500 and D7200 all use "Faster" up to ISO 800 and the new "Better Qual 2013" at ISO800 and above.
There is no doubt the high ISO jpegs from the Expeed 4 cameras are better.
Looking at the RAW files from Imaging Resource from the D5500, D7100 and D7200 in Capture NX-D and applying the same settings to them all (using the newer "Better Quality 2013" at exactly the same settings as well) the D5500 and D7200 look identical and the D7100 is almost identical as well in the noise department (and as good) but actually shows slightly better detail. The biggest difference is in the red swatch. The detail is nearly all gone D5500/D7200, while the D7100 is looking really good.
But overall this shows me that the there is a definite advantage to the D5500 and D7200 for jpeg shooters but NONE if you shoot RAW.
