Things got really exciting for me when I discovered by chance an article about "Retro Adapter" on the internet (google times and looks at the "Traumflieger page")! This adapters (available for a little over 10) and possibly necessary appropriate filter adapter rings are the lenses attached to the camera runs around and obtained, provided a little sensitivity, insane macro photos. The smaller the focal length the greater the image. Since then a new additional hobby of mine!
Thus, the NX has become even funnier and more versatile for me and you can see just in this "universe" which is actually possible for a picture with this chip.
So much for the camera itself, as others here have said certainly the most important.
Now to the much advertised "Smart Camera App". This is not really suitable for NX300m in my view. In contrast to the extensive functions such as are activated when the NX30, this tool has come trimmed with this camera that you can actually finds only the automatic mode in remote operation. All other functions are easily hidden. This I feel as huge impertinence, because it is probably probably give no update since for months not even everything is translated (Greek letters tangle in spite of the few existing functions).
Just shoot at night or my aforementioned macro shots are not made in the automatic mode and require a longer exposure time due to, among others things an external trigger. Since then only remains an expensive external remote control, or going through the self-timer. In addition, I would have this tool a way desired "Timelapse" So to create time-lapse photography. With Sony z. B. there is something free for all cameras with Wifi (eg also for Comsumer-HX50V camera).
I do not know where to complain or can put pressure on the manufacturer, but this fact has me in the favor of the company. Samsung (own some equipment) rather weakened and this reason alone I forgive, I also "only" 4 stars for the total package ! When the great miracles still to be done that one assumes this app or the appropriate firmware for NX300m, I will forgive also the last star to my knowledge currently acquired.
PS Samsung should perhaps revise the offer of flash units. Since there is nothing in terms of performance, price, this concept fits!
