Mike,

I have done a comparison using a slide that I scanned with Daves Epson V300 scanner.
Taken on a Nikon FM with 200mm f4 lens, and film is 35mm Kodachrome64.
My D2X exposure was by flash at 1/2 power, and the comparisons are straight with NO processing. Naturally the raw file can have any adjustments like exposure or contrast applied if required. The scanned version was at the scanners maximum resolution of 4800dpi as saved as a 16bit Tiff. Not sure what Dave will make of this as he has scanned loads of slides.

As the comparisons are screen grabs they do not reflect the true sharpness of the scan or photo versions. To example that I have attatched the photograph version that I reduced to 760 high then applied smart sharpening of Radius 0.1 Amount 80. So not much sharpening at all really.

Images attached :
1) Screen grabs of unprocessed comparisons with respective histograms.
2) Magnified versions. Note this is 1222 wide so needs opening to view properly.
3) Photo version at 760 pixels high.

Don
