The Nikon D4 will reportedly feature a 16.2 megapixel sensor, 11fps burst mode and the new Nikon WT-5 wireless transmitter. It will also support CompactFlash XQD memory cards, the newly-announced format based on the PCI Express specification, and will include an integrated Ethernet port.
Rumour has it that the native ISO will range from 100 to 102,400, expandable to 50 and 204,800. This would make the ISO range double that of the Canon 1D X, which has a maximum ISO of 51,200, and is said to be the D4's nearest rival.
