People has claimed that they continued to improve the video functions since the K-7. I haven't tried that yet. I was hoping that they had also tweaked and improved other properties of the sensor. But my impression is that the K-7 does better, though I need to make a side by side comparison on the same motif, in the same light. It comes down to the nature of the noise. There is something with the NX20 noise at high ISO that I don't like!
