Could you please upload the full sample set to the RPU?
In particular, the usermanual suggests that the camera produces two raw variants:
RAW images recorded with this camera have a resolution of 14 bits per pixel. However,
resolution is limited to 12 bits in the following shooting modes:
[ Long Exposure NR]
Continuous shooting (including continuous shooting in [Superior Auto] mode)
[ Silent Shooting]
Place camera in a stable position (tripod?, and the scene should be as static as possible, something horizontal, landscape-y), and take one normal raw, and one raw in
Silent Shooting mode, and upload both of them. Right now we have just one (12-bit) sample.
