Nikon really dropped the ball with the D800 and D600. Canon have really picked up their game with the 1Dx, 5DIII and 6D. The new 610 specs look very much like a feature plugged responce to the 5DIII and 6D.
For my wedding work, the 5DIII's quiet mode shutter is a game changer. It's good to see Nikon finally catching up with this, as usual a little late to the party. Hello cmos, hello full frame, hello live view, hello movie mode...and now hello quiet shutter mode.
It's not good that a camera in this price bracket and feature bracket has needed a warm over so quickly, but I guess that's a responce from the disasterous sales issues. How long will Nikon owners put up with this type of customer care or poor product development. The lack of silent mode is quite a biggie in the post 5DIII world.
