In our tests of these two cameras, after processing the RAW images with Nikon’s RAW converter, we saw about one stop of difference in the noise results in favor of the D700 at the D300’s highest ISOs of ISO 3200 and ISO 6400. This is to say that the D300’s noise score of 1.4 at ISO 1600, basically matched the D700’s score of 1.3 at ISO 3200. The D300 scored 1.95 at ISO 3200 in our test, nearly matching the D700’s score of 2.0 at ISO 6400. Finally, the D300’s score of 2.83 at ISO 6400, closely matched the D700’s score of 2.8 at ISO 12,800. At ISO 800 and below, though, the two cameras showed very similar results.
