The D800 is the most exciting piece of equipment to emerge from Nikon since 2008. A pull-out reference card gives quick access to the camera's functions. UK author Jon Sparks gives an in-depth guide to using this impressive camera, with hints and tips. The D800 is the biggest news to emerge from Nikon since 2008, when they introduced their last all-new full-frame DSLR, the D700. The D800 is a complementary or alternative to Nikon's own new professional camera, the D4, but at half the price. The D800 packs in more resolution than any other full-frame DSLR by a huge margin, with more than twice as many pixels as the D4. Built for today's multimedia photographer, the D800 has a powerful 36.3mp. The camera's extremely high image quality comes from a body that weighs less than any other Nikon full-frame digital camera, making it ideal for landscape, commercial and studio photography, but with the flexibility to appeal to enthusiastic amateurs who can justify its price tag.
