mpgxsvcd: The D7200 definitely shows a high ISO noise improvement over the D7100. It looks like it is on par with the 7D MK II for about $500 less.
I don't know- I spent a lot of time looking back and forth between the D7100 and D7200 for ISO 1600, 3200 and 6400 and I have a lot of trouble seeing a visible difference between them in RAW. It's not totally absent, the D7200 is very slightly cleaner but I doubt the difference would be photographically relevant even at huge enlargements. There is a clear difference in colour noise between these cameras and the 7D Mark II and A6000 to my eye but I'm surprised at just how similar the two Nikons are. Makes you wonder if it's still the same sensor.
Jefftan: I read the review. it said 18-55 mm can't deliver the full 24MP resolution but did not do any test to prove itSo this is just an opinion?
No, they're not stupid, just cynical. It's a ploy to upsell people to Nikon's pricier lenses.
