Seems to me that DR is pretty good with this camera. I didn't do any direct comparison but it might be as good as my DSLR (Pentax K10D).
Image shot in raw, converted with ACR and post processed in Photoshop. Exif embedded in image.
PS: I didn't use the S100FS' extended DR feature, as it's a jpeg thing...
