As well as shooting our studio test scene at each camera's lowest sensitivity we also shot it at ISO 800 and 1600. As you can see the approach taken by Canon (clean data in, less need for noise reduction) really pays off at ISO 800 and 1600 where it demonstrates far more detail and less visible noise than any other camera here. Between the DSLR-A100 and D200 at these high sensitivities the A100 appears to maintain more detail.
