Exif "ISO" value always zero when reading Samsung

Hi,
I just bought a new Samsung GX10 camera (very like the Pentax K10D), and I have been trying out XNView on the files it produces.

I noticed one odd result. If the camera is set to generate a RAW (DNG) file and JPG file for every shot, the EXIF data for the DNG file always shows the sensitivity ("ISO speed ratings") as zero. However the value in the matching JPG is correct.

Is there any easy way to debug whether this is actually a problem in the DNGs produced by the camera, or whether it's a problem in XNView?

Regards: Colin

Is it possible to have a sample?

Hi Colin;

it is probably the same bug as reported here for the Pentax RAW-files.

@Pierre: Any news about the Pentax problem, i did send you a sample a while ago?
