I'm sure this has been discussed here somewhere, but I can't seem to construct a search that will tease it out. How does the D60 perform at higher iso settings, particularly as compared to the D200 and D40? Since it has the same sensor as the D200 (right?), I would expect it to give about the same performance unless there are some firmware upgrades that help out. But the D40, at 6.1MP, might be better. So, any experience out there to provide guidance? Thanks for responding.
