For what it is worth I think Thom hit it right on the nose on the D100. I have had mine now for a couple of weeks and, as I am not very digital literate,I am struggling to get it just right. My only real complaint is having to shoot largely in the NEF mode. This *really* impacts how much storage space one needs for even a " day shoot" in the wild.
Still, I am keeping mine. It can make very good pictures and that is all I really want.
PS. On an entirely unrelated subject I read today that Fuji wil soon announce a Velvia 100 speed film with even finer grain than Provia F. Any knowledge of this?
