Summary: Since Nikon is preparing to introduce a new line of high-resolution cameras, I decided to not purchase the Nikon D3 - 12.1 M this year. Instead, I purchased the Nikkor 18-200mm lens for my Nikon D200. The lens is excellent and satisfies me while I wait for the next wave of sensors.
Summary: Where do I start? It's mediocre camera at best in professional world. My Nikon F5 is just as fast and produces perfect quality photos as opposed to D3 as well as being useful in places like Alaska where you can't easy charge your battery on D3. My Sigma SD14 outperforms D3 in quality and color accuracy at ISO100 RAW. My Hasselblad and 45 View cameras can never be touched in image quality by D3. The only OK aspect of D3 is it's performance at 3200 or so.
