As mentioned, I've realized quite soon that I had got spoiled by shooting with the Pentax K-5. Samsung NX is very far from the K-5 standard at high ISO. Now, the Samsing NX20 of course has a Samsung sensor. One that is presumably related to the Samsung sensor in the Pentax K20D and the Pentax K-7. Not exactly the same, but certainly related, perhaps like a niece or so ;)
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!

| A more pleasing shot at ISO 6400 from the Stockholm sub-way yesterday. But then of course, there is more light in this shot, and high ISO always looks better when there is plenty of light, and then one could perhaps have shot it at lower ISO? Both shots were with the Konica Hexanon 40mm f1.8. |
