When the Nikon D800 was announced, the specification that got everyone's attention was - and to a large degree still is - the massive pixel count of its 36.3MP CMOS sensor. When a moderately-sized full-frame DSLR body aspires to go toe-to-toe with medium format cameras and backs at a fraction of their price, other attributes can seem secondary, but 3, 1/2 years since Nikon released the D700 Nikon has updated much more than just the resolution. The D800 has a significantly more advanced feature set than its predecessor, particularly in terms of its video capabilities that make it, on paper at least, a viable and tempting option for professionals.
