I have had my D300 for only a week, so I may be screwing up some settings. However, I am having terrible results in regarrd to noise. I have used a D70 for 3 years. I bought the D300 in search of better high ISO results. In comparing shots from the D70, with no noise reduction, against the D300, with High ISO noise reduction on low, the D70 runs rings around the D300 at equal ISO settings. The noise on the D70 has a smooth texture that is easily removed in pp. The D300 noise is very grainy, like grains of sand. Applying just moderate amounts of sharpening makes the image look like it is covered with dandruf. I only have a couple of days left to return the camera; but, before I do, I was wondering if anyone else has encountered anything similar, and if there is anything that I should try before giving up on this camera. I love the way this camera handles, and really do not want to give it up; but, if I can get better results with my older camera, there is no sense in keeping the new one.
