The King of DSLR, the Nikon D4 gave birth to a baby; the D800 was born to replace the venerable 30 months old D700.
After the lack luster response to their new "small sensor" Nikon 1, Nippon Kōgaku came back with a vengeance and caress their fan boy with a whopping 36.3 mega pixel CMOS inside a solidly build body!
This is what Nikon said about their new sensor:
"The D800/D800E render levels of texture, nuance and detail to your
photography that, until now, have been the exclusive domain of the
complicated medium-format system.
Define every eyelash, every line in
tree bark, and every shimmer of light. Savor the exceptional depth in
your still images — with the combination of an astounding 36.3 effective
megapixels, the world's highest*, and the outstanding performance of
NIKKOR lenses, you can.
