After hundreds thousands of shots with the D90 I can get what I expect, knowing that the usage limit for the D90 is ISO 400. I rent when i need D700 or D3s for works at 800 iso and more.

I shoot in NEF and all settings (all) are manual. I have thousands of stunning images taken with the D90 also in critical condition.
In some photos I posted here after trying the manual settings i tried the aperture priority. Up to now all the images that I use for my works are jpgs, converted and not modified NEF files with View NX
Again, this forum now iis full of D7100 pictures at 3200 ISO that appear perfect.
Unfortunately, these are not the results that I got.
What I would like to share with you is to know if after 5 years from the release of the D90 from a new camera concepts like the D7100 might be expected to arrive in 1600 with good iso files.

The D7100 has lower noise than the D90 at equivalent reproduction sizes. The only way you're going to convince yourself of this reality if you shoot the exact same scene with both cameras using the same exposure and do the comparison yourself. Noise is 99% dependent on the absolute exposure and looking at low-key exposures from one camera and comparing those to the noise you remember seeing from a high-key exposure on a previous camera is a surefire recipe to convince yourself the new camera has more noise; i can show you a D3s ISO 1600 image that is noisier than a D3s ISO 6400 image, where the difference is simply the absolute exposure (ie, the amount of light that the camera allowed to reach the sensor).
