As updates go, the Nikon D800 is a pretty major one. Compared to its predecessor the D700, Nikon's newest DSLR features an impressive set of key specifications, and subtly refined ergonomics, too. After more than three years we expected the D800 to outclass its predecessor, but products don't exist in a vacuum, and it wasn't long after the 12MP D700's announcement that Canon brought out the movie-shooting EOS 5D Mark II.

Not only was the 5D II Canon's first video-equipped DSLR, but at 21MP it offered a class-leading pixel count, effectively equal in resolution to Canon's professional EOS-1 Ds Mark III. The D700 won plaudits for its versatility, low light image quality and 51-point autofocus system, but it couldn't compete with the 5D II on resolution, or of course, video. 

The D800 changes all that. Compared to the D700, the D800 is a thoroughly modern camera, boasting a highly advanced feature set for both still and video shooting. At 36.3MP the $3000 D800 comfortably eclipses its competitors in terms of pixel count and makes the $8000 Nikon D3X look distinctly irrelevant, too.

Compared to D700: Specification highlights

  • 36.3MP CMOS sensor (compared to 12.1MP)
  • 15.3MP DX-format capture mode (compared to 5MP)
  • 25MP 1.2x Crop mode
  • 51-point AF system with 15 cross-type sensors, rated to -2EV* (compared to -1EV)
  • ISO 100-6400 extendable to ISO 25,600 equiv (same as D700)
  • 1080p video at 30, 25 or 24 frames per second, up to 24Mbps, with uncompressed HDMI output and audio monitoring options*
  • 3.2", 921,000 dot LCD with anti-fog layer* (compared to 3in, 921k-dot)
  • Maximum 4fps continuous shooting in FX mode, 6fps in DX mode** (compared to 8fps in FX mode)
  • Advanced Scene Recognition System with 91,000 pixel metering sensor* (compared to 1005-pixel)
  • 'Expeed 3' Image Processing*
  • Dual-axis Virtual Horizon (on LCD screen/viewfinder)(compared to single-axis)

* Same or almost identical to Nikon D4
** Maximum frame rate in DX mode is dependant on power source

We've had a D800 in the office for a few days, and we've spent that time shooting with the camera not only in our studio but also out in the big, bad 'real world'. We're some way off being able to publish a full review, but I wanted to share with you some first impressions. You've already read our in-depth preview, and you know what the professionals think, but now that we've got a production sample to play with, I want to give you an idea of what the D800 is actually like to use.


The D700 was a generally pleasant camera to hold and use, and so is the D800. Nikon hasn't made many drastic changes to the handling experience, and those that it has made are broadly in line with Nikon's design philosophy for 2011/12. Gone is the 'traditional' MF/AF-S/AF-C focus mode switch on the lens throat, to be replaced by the same combined MF/AF switch and AF mode button control that we've seen on the D7000 and D4. This updated approach to focus mode selection is nice and neat, because it associates all of the many options with a single physical control point, but as I pointed out in my recent article about the D4, it does make switching between AF-S and AF-C less rapid than it used to be.

 In general terms, the D800 handles a lot like the D700 that it replaces. Key controls are in almost exactly the same places, but the D800 does benefit from a redesigned live view control and drive mode dial. The screen has the same 920,000-dot resolulution as the screen used in the D700, but like the D4, it features improved moisture and dust-proofing. 
Not only does the drive mode dial lose the D700's 'Lv' position, it also features firm detents, so with the dial unlocked it is possible to tell by feel when you're scrolling through the various positions. This is a small change, but a very welcome one, and one which (with a little practise) makes it possible to switch drive mode with your eye to the viewfinder. 
On the D800, just like the D7000 and D4, live view gets a dedicated control on the rear of the camera, with a physical switch for still shooting and movie shooting modes. In movie mode, the framing reflects the 16:9 aspect ratio. You must be in movie shooting live view mode to initiate video recording, via the red button on the camera's top-plate.

Of more signficance to the average D7000 user will be the D800's updated drive mode dial and dedicated live view switch. Live view mode on the D700 was very much a 'first generation' implementation and although effective and useful, setting it via the drive mode dial was a pain, especially if you needed to grab a quick high or low-angle shot.

Improved Automatic ISO Sensitivity Mode

The D800's automatic ISO mode is inherited from the D4 and is improved over the same mode in earlier Nikon DSLRs. Previously, auto ISO customization was minimal, and consisted simply of an option to set the maximum ISO and minimum shutter speed when the camera was used in auto ISO mode. The currently-set ISO counted as the minimum ISO sensitivity (and in fact still does). This system was fine for shooting with a fixed focal length lens, but less useful with zoom lenses, where a 'safe' minimum shutter speed at either end of the focal range might be several stops apart. 

In the D4 and D800, Nikon has (at long last) added an 'Auto' option to the minimum shutter speed options, which allows the camera to automatically set the minimum shutter speed based on its knowledge of the focal length that you're working at. This response can be biased in 5 steps, from 'slow' to 'fast' depending on whether you'd like the camera to err on the side of slower or faster shutter speeds. A small change but one that takes Auto ISO a little closer to being the 'set and forget' function that it should have been long ago.
