Last crop is especially good example that there is something wrong with this camera, because you should not see such bad posterization in the DNG files. Not even in Fine quality JPEG. So it's definitely weird.
BTW, in your last post, you mentioned one important point that could be the clue why I cannot reproduce your problem! You are using AdobeRGB while I'm using sRGB! I will give it a try with the Adobe RGB. Could you please try the sRGB option?
I also asked you for your camera settings. Here is how you can extract them:
Go to Menu >> Key Custom options >> Reg. My Settings >> and in the appeared "
Chose a Destination" window select "
Card". Then simply select one of the 6 available slots to save your actual GRDIV configuration.
Now connect the camera to computer (or SD card via the card reader) and go to
Myset folder, where you should see something like
myset01.ifo. Then simply upload the ifo file to your post (using
Post Reply button. Quick reply does not have the ability to attach files).
I will try your configuration on my GRDIV, just to see if it has something to do with the camera settings or not. But my personal opinion is that it's something HW related.
