Just three days after Canon announced a pair of pro cameras, Nikon unleashed its own duo of high-end digitals: The ultra high-end D3 and the still really high-end D300.
It leads with the Deathstar of SLRs, the D3. The biggest change is, in fact, one of bigness. Nikon equipped the new camera with a 36x23.9-millimeter image sensor thats nearly as large as an old 35-milimeter film frame. Previously only Canon made these full-frame sensors, which capture extreme wide-angle shots and have larger pixels to soak in more light.
