First Impressions of the Nikon D4

Making substantive changes to an established design is risky, and although most of the differences between the Nikon D3S and D4 take the form of improvements in the newer model, the D4 isn't perfect. Here's a quick overview of some of the aspects of its operation.

The D3S was a pretty big leap in terms of noise and detail at high ISO sensitivities compared to the original D3, but viewed at 100% on screen, images from the D3S and D4 are very similar, even when you get up into their highest ISO sensitivity settings. Where the D4 scores, unequivocally, over the D3S is its extra resolution. An increase of 4MP might sound relatively modest, but the D4 can capture noticeably more detail than the D3S across its entire ISO span. In the table below you'll see four 100% crops, from simultaneously-captured JPEG and Raw pairs at ISO 200 and 12,800 on both the D3S and D4.
