At ISO 100 the D7200 and D810 have really low read noise, around 2.5e- and 3.2e- respectively. Both also have virtually 14-bit of dynamic range which fits their 14-bit AD converters.

ISO 200-400 has the read noise drop a reasonable amount while keeping a very good dynamic range.

ISO 800 doesn’t have much of a read noise drop so the only thing dropping is the dynamic range. After ISO 800 the read noise stagnates so image quality just goes down hill.
