The picture quality is even with the kit lens (18-55) exceptionally well (much better than it was in my SLR), metal bayonet, zoom and focus are good to use, and also important not rotating front element that prevents the use of a polarizing filter , To estimate correctly, I have learned to set focus point with a fingertip. In the autofocus mode then you can still manually adjust the focus and per Magnifier check just awesome.
The now announced Samsung NX500 will offer 28 megapixels and the focus should be 25 milliseconds faster instead of 20 now. Whoever is not necessarily reliant is well served by the NX300M, especially as the camera currently is unbeatable.
In addition to the camera, I have the following accessories in use: Camera Case Kata DC-431, spare battery and external battery charger, anti-reflection film for the display (helps in strong sunlight), wrist strap and belt from Peak Design (the supplied belt I have not even unpacked) and four filters (dust, ND filter, polarizing filter and a close-up lens, with the surprisingly good macro shots are possible). This brings me to one third volume and weight compared to my SLR equipment. Of course, one is somewhat limited with this equipment, and of course I can with a large camera while holding a large lens and a large flashgun much better in spite of everything, because of the great picture quality, an attractive processing and thoughtful usability can I issue a strong buy recommendation.
