I have been attempting to shoot pictures at my daughter's swim lessons without flash. Today I shot with my D70s at ISO 800 and ISO 1000. The shots at 800 looked ok, but at 1000 there was a lot of noise. A week earlier I shot with my D60 at 1600 (slower lens) and again there was a lot of noise. Would any of the newer models handle the higher ISO without as much noise?
