Here is a Preview of the Nikon D4 that I made after getting a chance to spend some time with this camera. There are so many amazing features that have been added to this new DSLR. The ISO capability has gotten better once again and this is the first Nikon Pro camera to take a leap into serious video making territory.
Professional photographers know the drill: every few years, Canon or Nikon announces a game-changing DSLR, often prompting top photogs to unload their complete kits and switch to another system in a never-ending attempt to shoot with the best.
The Canon EOS-1D X is the company's flagship professional DSLR (2011). The 18MP camera is built around a full-frame sensor capable of shooting at up to 14 frames per second (12fps with AF), allowing it to replace both the 1D Mark IV and 1DS Mark III in Canon's lineup. Despite looking like previous 1D cameras, it's been extensively reworked and includes more professional video features than any other Canon DSLR.
