With a DxOMark score of 76 the NX300 falls just behind the $900 16Mpix Sony NEX-6 (scoring 78 in our benchmarking) with its similar size APS-C sensor. Despite the lower pixel count of the more expensive Sony, the NX 300 has similar Color Depth and Low Light capabilities but a slightly lower Dynamic Range of just under +0.5EV. Both cameras out-perform the smaller sensor in the Panasonic Lumix DMC-G6. In Dynamic Range, the NX300 has around a +1 stop advantage, dropping to +2/3 stop over the G6 in the Low Light score. However, the biggest gain to be seen is in Color Depth where the NX300 has a +1.5 stop improvement over the $750 Panasonic Lumix DMC-G6.
As for the NX210, the DxOMark score of 71 puts it on a par with the similarly priced ($599) Olympus Pen E-PL5 at practically every metric, Color Depth, DR and Low Light ISO though behind that of the competitively priced ($500) Sony NEX-3N. While the Sony has similar Color Depth and DR to the Samsung, it has just under a ½ stop advantage in Low Light scores.
