Review on the 5R?
Well it has a way better interface w/ the 5N, one button to access shooting mode, really fast AF that the 5N but the 6 is AF is still a bit faster, added dial control and FN button adds a BIG difference in control and accessibility of different camera functions. The 16-50mm PZ Lens is more awesome compare to the 18-55mm although I think I'm still gonna use the SEL50F18 more.
Ergonomics is still great and same w/ the 5N although I have to admit mas masarap sa kamay Nex 6 kasi di masyado crumpled kamay mo. IMO Nex 5R is a "Fun" camera, where the Nex 6 is more of a "Purist" camera.
Yaman? no, I actually planned to only keep one, di lang ako marunong siguro mag-appreciate ng Viewfinder kasi noob that why selling my Nex 6.
