As with the D200 on the previous page the Canon EOS 40D comes to this comparison with a two megapixel (256 vertical lines) deficit, however it does appear to stand its ground a little better (helped somewhat by slightly stronger sharpening)*. The D300 does eke out a little more detail in some areas of the image and there's definitely a feeling of more natural texture response on the Baily's label crop (second from bottom). Overall however apart from the base sharpening differences there's not a huge amount between these two cameras and certainly in print it would be very difficult to pick a clear winner.

* The difference in sharpening with the D300 is not as significant as it was with the D200. If you prefer your images sharper (although obviously with the risk of sharpening halos) you can turn sharpening up to 4 or 5 from the default of 3, for comparison download links are below.
