1) Exposure: despite 3 rotating wheels it was not possible to make the first firmware versions directly via rotary control exposure compensation. With firmware 1.10 this function is now at least on the flat large rotary knob assignable (in addition to IFN-key button on the lens or above +, but represent only an intermediate step). Supplement 29.01.2015: with Firmware 1.20 it is now possible on the other rotary wheels.
2.) AE bracketing only 5 shots possible: this was at the NX30 even 3 shooting (with 5 does not) go Samsung here the opposite way and saves programming time. Must be resolved quickly via firmware! Moreover, in my view, is the serial speed in the 5 shots of improvement *, ie the consideration to accept the 5 shots halt and afterwards again to erase recordings is only a weak solution. * The comparison is here a Sony A77I.
3.) AF Tracking: only in Live View with Touch AF possible, but again very good! At least I have not yet figured out how it should go only by the viewfinder. Overall, reinforces the impression that Samsung (like Sony) want to settle by others and this will offer (next to the sensor) va a Live View-oriented camera plus the special i-FN function on the lenses. Since Samsung is strong in tablets etc. active, again no big surprise. A sports photographer but is determined not handle ... apart from the fact that it comes from Samsung also are almost no suitable lens for this purpose via Live View in the stadium on the sidelines ...
Supplement 29.01.2015:
4.) The Point Zoom only works with Samsung lenses by forward turned on the lens. There is no way this assign a key on the housing.
5.) The Optical Image Stabilizer can only (awkward) exclusively via the menu and are turned on. Again, this is just not possible with a key. Furthermore, the setting for all user settings applies. Who defines so for a tripod for example, a separate user settings (on C1 or C2) must always consider whether the OIS was turned on or off before.
Otherwise, I'll have additions which once strikes me ... I'm going to keep the camera because of their many advantages (s. Other comments) until further notice ;-)
Supplement 03.09.2015:
Is 6.) problems also with the Custom mode: for example it is not possible "in" a C-mode for example to change the Iso time in between to activate the preview and so to make with modified ISO setting on. Then again "fallen back" to the original Custom setting with original ISO. It is for example not possible to save different speeds in each burst as "Custom Mode" and then using custom mode (C1 or C2) call.
