Since a week or so my Samsung NX 1000 camera is capturing completely black photos. Not all of them, just about the 50%.
(The first one after switching the camera on or changing mode normally is ok)
The photos are really completely black (I am in RAW mode and checked them in Lightroom, too), no detail, no noise. So it does not seem to be a problem of underexposure.
I tried different lenses, different memory cards and even upgraded the firmware to 01.15, without success. Switching to other capture modes or changing to JPG does not help neither.
Does anyone have an idea why this might happen and what I could do to fix this?
