"While I fully agree with you that the D100's standard sharpening in JPEG mode is lacking I think you'd likely find that you need to sharpen the images from any camera far more heavily for printing than you would for normal viewing."
You are absolutely correct. I use a standard unsharp mask on everything I print from slides scanned by my Coolscan IV. Really makes them work on a print. So, I guess having to do the same on all D100 images I want to print should be no big deal. That does mean I will have to shoot everything on NEF, doesn't it? Am I correct that anything I shoot in camera on jpeg will lose information and there is no way to restore it in Photoshop? In short, a "soft" jpeg stays a soft jpeg?
As far as action shots are concerned, that is not an issue for me. I cannot remember the last time I shot sports, although I might try to get an occasional bird in flight.
I will keep my eyes open for the contrast problem. That could become an issue as I do a lot of landscape work. Contrast can be a huge problem with slide film, as you know, and has made me turn to negative color in some situations to mitigate the "blown out highlights" syndrome which, as you know, can ruin an otherwise good shot.
For those of us who have only shot with Coolpix P/S cameras, would you mind telling what settings on the D100 you have found best so far?
