   

Advatages * Image quality comparable with its peers * Excellent viewfinder * Superb high resolution LCD monitor * Automatic chromatic aberration correction improves performance from all lenses * Punchy but not un-natural colors (and plenty of control if you want to change them) * Good dynamic range - and Active D-Lighting to help make the most of it * Useful in-camera RAW processing option * Excellent degree of customization (reversible dials and meter ease transition from other systems) * Fast Autofocus with useful control options * High sensitivity performance up there with the best we've seen * Sophisticated wireless flash commander built-in * Programmable FUNC button with useful list of functions * Configurable 'My Menu' (and option for FUNC button to access the top item on it)

Advantages * Excellent build quality, tight shut lines, quality materials * Instant power on, very responsive in-use * Auto-focus assist lamp rather than requiring flash to be raised * Control over high sensitivity noise reduction * Customizable automatic sensitivity (ISO) * Easy to use playback / delete combination * Status LCD panel on top of camera (we still like them) * Fast continuous shooting mode * Good SD card throughput and USB 2.0 transfer speed * Extensive retouching features including D-Lighting, Red-eye reduction and distortion correction * Good battery life and precise charge-level indication * Dedicated help button provides in-menu assistance * HD video

Disadvantages * Over-enthusiastic metering a little prone to blown highlights * Very soft (default) JPEG output compared to its peers * We believe more of the captured dynamic range could be incorporated into Jpegs * Menus getting long and complex (though well organized and differentiated) * Bundled software pretty limited * Arbitrary 100-shot limit on continuous shooting * Disappointing automatic white balance performance in incandescent light * In-camera RAW conversion could provide more control * Video capabilities limited in a number of ways REFERENCE: nikond90/AnswerViewer.do?requestId=
