throughout the industry, the D4's body is strikingly similar to its half-decade-old predecessor. There's no edgy new design to speak of, and all of the controls are exactly where you'd expect them to be. That's not to say Nikon didn't make a few tweaks, however. First, there's a full set of vertical controls for firing the camera and adjusting key settings without awkwardly reaching around the body to access the buttons up top -- an improvement that's sure to be appreciated by portrait and wedding shooters. The main shutter release was also moved slightly forward, for a more natural feel, and a dedicated movie capture button was added. There's also a new pair of joystick-like controls for navigating menus and moving around an image while zoomed in during playback. Overall, the additional controls improve upon the interface without introducing clutter -- an advantage granted by the generous body.
