Voigtlander 12mm on NX10 pic
Hi, yeah - i probably wouldn't take both (although i could convince my wife to take the other
The Sony 5n has a better shutter response time and faster frame rate, Better in low light by a good margin, and is smaller, but less comfortable to hold.
The NX10 has a hot shoe and better access to manual controls and changing modes - it's LCD is wonderful as well - but it's mainly the hot shoe and the fact that i already have the 50-200 for it which is a great lens - as in the 30mm
I also found out that my 21mm f4 voigtlander doesn't work on the NX mount, which is disappointing as it's my most used focal length.
The NX1000 is looking interesting as a dedicated 30mm f2 camera - as long as it's buffer is not useless with RAW files (like the NX200)
