The
Samsung NX200 has above-average JPEG processing for a sub-$1,000 camera. Combined with its relatively clean images off the sensor, its noise profile is quite good. The eagle-eyed will still see artifacts--especially in dark stretches of high-ISO-sensitivity photos, like
this, and on edges. But overall I was really impressed with the quality of the noise reduction and compression, as high as ISO 1600 on some photos.
