We've had some time with a pre-production D800 and have prepared a detailed in-depth preview. Nikon's latest DSLR boasts core technology borrowed from the top-end D4, married with a 36.3MP CMOS sensor that comfortably eclipses the rest of the DSLR market in resolution terms. As well as first impressions of handling and operation, and an in-depth look at the D800's specifications we've also dived a little deeper into the D800E, the D800's sister model, which cancels-out the effect of its anti-aliasing filter.
