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 DSC-R1's aggressive noise reduction is most noticeable at ISO 800 where some detail is lost although the overall effect is a relatively clean image, at ISO 1600 noise is more obvious especially in the dark area of the label, that said it does look better than the E-500. The overall winner though for higher sensitivities remains the Canon EOS 350D which delivers good detail and low noise at ISO 800 and 1600.
