I get in my second NX1 camera today and it was having the exposure drift problem so after setting it to the same settings as my other one i found the one thing that is making the problem a extra menu of items with one setting that needs to be changed.. Here is what i posted on Facebook Look at the back of the camera lcd you will see a arrow at the top of the screen in the center. Tap on it and turn off auto display brightness.. that was the only other setting my older camera had changed and now
The two last firmwares have improved HD video, DOF, 4k DCI (not tested, if anyone can confirm ?) and fixed some bugs. UHD is great in good light, better than GH4. But we really need control over noise reduction on low ISO. In low light or in dark areas of the image, some details are washed away, the GH4 is noiser but retain really more details.
