Bottom Line
Whenever a new piece of top-level gear comes along, there’s a rush by many pros (and more than a few amateurs) to get it right away. While the D4 does outshine its predecessor in many ways, we would not call it an essential upgrade for still shooters who already have a D3s. If more resolving power or the 1-stop improvement in noise control mean a lot to you, then it could make sense to upgrade from your D3s. But, if the D3s’s ultra-clean low-ISO images matter more to you, then it might not make sense to move to the D4.
Videographers, however, should definitely consider the D4. Besides the uncompressed output and all the audio extras, the camera’s noise control should allow for appreciably more versatile shooting with video.
Shooters who split time between stills and video might have a harder time figuring out whether to upgrade. We think that the versatility of the video options should be enough to warrant the step up. But, if you need more reason, the video features and the advances in the still-image quality combine to make the D4 practically irresistable.
In any case, the D4 proves that as amazing as cameras have become, they can—and will—get better still.
