Just my 2c. I used only D7000 and not D7100 in DX format, but latter is better at higher ISO (at least what I hear).
it is true that noise issue is very subjective. I do not think anyone will do a portrait at ISO 12,800, but anything below 1600 is quite usable for paid work. Before i'll start with some samples at ISO 3200 (D7000)I want to show samples from less capable cameras at ISO 1600:
1. 9 year old D70 at ISO 1600:
2. 2 year old D5100 at ISO 1600:
3. Now on to D7000. This is a snapshot of my daughter enjoying some candy and movie. After PP it's sharp enough to my taste:
4. A snapshot on a subway. ISO 3200. the guy cut out pages in the actual book to protect/hide his device. after removing noise in PP and some sharpening I can still read some of the words on the Nook and in the book itself. No cropping is done just to show you the original framing:
5. Now let's step up into ISO 6400 territory. this one quite a crop and it still good example that ISO 6400 on D7000 can be used quite successfully:
6. ISO 10,000 (in Auto ISO mode). Maybe not professional work, but quite a value for the family portfolio:
7. And my favorite example, which I shared many times and the only image I have at the highest ISO for D7000 - ISO 25,600.
