The D3's high ISO is really impressive I'll remain at least somewhat skeptical until we can get a D3 back in the lab and test it under controlled conditions, but Nikon showed some incredibly impressive prints at the event. They had enlargements that must have been 30x45 inches or more in size, comparing identical shots taken with the D3 and Canon EOS-1D Mark III at ISO 3,200 and 6,400.
After the disappointment of the D2H, I have to say I was taking Nikon's claims of low noise at high ISOs with a rather large grain of salt. When I saw the aforementioned prints though, I was literally flabbergasted. The D3 didn't just surpass the 1D Mark III, it far surpassed it. Well, that may be a little strong; the Mark III is a fantastic camera, but the difference between its images and those from the D3 was anything but subtle. As I say, I'll remain a skeptic until we can test a production sample of the D3 ourselves, but if the images shown had any basis in reality (and Nikon would be foolish to have doctored them in any way), it looks like there's a new leader in the high-ISO / low-noise derby, and it's the D3.

he 3-inch LCD takes up more real estate on the back. A plastic screen cover is still available for the D300, but is not shown here. The LCD itself is reinforced with tempered glass.

. The Nikon D300 uses and EN-EL3e battery, which will drive it through 1,372 shots on a single charge. The optional MB-D10 Multi-Power Battery Pack adds more than two frames per second, taking the D300 to 8 fps, probably its most enticing feature. But it also allows a battery to be kept in the camera body to supplement the battery grip's input. Other designs use a tower that goes up into the battery compartment, which introduces a few problems, including packing the grip in a camera bag when it's not in use. The MB-D10 is easier to use, and packs well.
The reason it's called a Multi-Power Battery Pack is that takes other kinds of batteries, including 8 AA cells, and an EN-EL4a, the same lithium-ion battery that the Nikon D3 and D2x use. Now we're talking power: 11.1v 2500mAh to be exact. No word on how many frames you can get with that pack, but I'm sure it's significant.
