6D + Canon 50/1.8 or D600 + Nikon 50/1.8? Help me decide.

hello

i would say fun, lightness to shoot with a 6D, easy and fast settings and of course as you say it quietness.

Exposure is very dependant of the focus point but the result is great on this FF ( i replaced a nikon d80 for a d200 for that reason some years ago).

Sure a D300 like body feels more serious in the hand the first day you get the 6D, but not a few days later, anyway the D600 body hasnt that feeling too.

Of course we always come back to a point where we have to decide what  autofocus quality we need and that is personnal.

The best is to test each camera a few days if possible

Good choice
