In general, a very positive device. From all tested by me in a close price category PENTAX K series Kit (very poor photo quality, and not Full HD Video) SONY Alpha 290, 390 Kit (not bad, but I would like a video). CANON EOS 550D Kit (They were unreasonably expensive with almost the same parameters of the Nikon D3100 Kit), FUJIFILM Expensive and lying colors (embellishes by increasing the contrast, as a result, in some photos there is darkness under the eyes).
