The Nikon D4 has proven to be the best performer in the Nikon family. Once owned the D3S I can say you won't be disappointed with this Low Light Gem.
Brilliant professional tool
If you want to get a shot in any condition, this is the camera to have. I bought this originally for sports but realized quickly that it is a lot more versatile than my D800. The keeper rate is high, the focusing and image quality is top notch, I did sports, wildlife, portraits, landscape... in my opinion it is perfect for anything unless you can't really live without 24 or 36 Mp...! I found the accuracy of the shot to be incredible, colors are excellent even at 20000 ISO...! What else can we have...? Of course there is room for improvement with everything but as far as I am concerned, this is by far the best camera I ever had and I had a LOT's OF CAMERAS in my time of different brands. The XQD card is blistering fast, I write RAW to XQD and JPEG to the CF. The fast frame rate is incredible, it just keep shooting... the focusing is easy to work out compared to the new Canon AF for instance and it is lighter than my old Canon EOS-1ds Mk3 I had. About 150g more than my D800 which is not much at all. Actually this camera is BETTER BALANCED than the D800 + the viewfinder is bright, basically, as you can see, I am a very happy owner. I still did not have the need to try the flash exposure compensation with distinction between the background and foreground, I hardly use the flash with this thing. In my opinion an excellent, robust photographic tool.Read full review
