The camera was bought, because I found it annoying constantly lugging a heavy DSLM.
About the data of Samsung NX3000 and its workings have been reported good and detailed in the other comments. Therefore, I come straight to the point.
The biggest problem: ----- Autofocus -----
The Samsung will not fire when halfway dark images. The annoying without end. In addition, the autofocus needs felt an eternity until the picture is in the box. Anyone with children is guaranteed unhappy with the device because the device 1. snapshot is not suitable, and 2 can hold a child in the world as long as quietly to the camera closes.
I had the Samsung with a children's paradise. The camera could not cope with the hectic movement of people. It emerged smear (Ghost effects) on almost any image. No matter what mode I chose.
My now 3 years old Canon triggers instantly and photographed my child in mid-leap in its full glory. Unthinkable with the Samsung NX3000.
---- For what the Samsung NX3000 is well -----
If you want to shoot a stationary subject in good light intensity, then you are using the device properly guaranteed. These requirements also the autofocus dissolves sufficiently quickly. The image is razor sharp. The lighting effects captured great and the simple handling easy.
--- Conclusion ---
The quality is simply not enough to me, and I'm not demanding. If you have family, then you can forget about the device. If you want to take pictures on the other hand resting on a lawn or take a shamrock in Macro Mode, the Samsung is super.
It seems at first sight an unfair SLR like the Canon EOS 1100D compare with the system camera from Samsung. I find, however, that a comparison is legitimate because the system cameras eventually want to be small DSLR. It remains to consider the the NX3000 is relatively new in contrast to my old Canon EOS (2011/12).
Even for a price to the 300 I find the Samsung NX3000 too expensive. Especially since my EOS now just costs so much.
I have returned the NX3000 again.
