#4. "RE: 7100 : what to expect from packing 24 MP in a DX sensor" In response to In response to 3
Most probably you're right for noise cancellation , but this is with the hypothesis that each pixel generates the same amount of noise than the D7000. If it is not the case, and the "individual pixel noise" is greater on the D7100, then what is diminished by summing up random noise is compensated by the higher noise intensity. Otherwise, why not having zillions of pixels ?
For the Dynamic range at high ISO, what do you think will be the effect ?
