If you've read our Sony DSLR-A700 review you may already have seen this comparison. Both cameras have twelve megapixels, both have the same vertical pixel count, the D300 has 16 extra horizontal columns but that makes no difference. A quick scan down these crops indicates that there's very little difference in absolute image quality apart from perhaps slightly more low contrast ('texture') detail from the D300 and a very slightly more conservative approach to sharpening.
