Citat:
The D3s's sensor is an evolved form of the original D3's 12.1MP full-frame sensor, using a different structure to improve the signal-to-noise ratio while shooting at higher ISO ratings, along with new algorithms for better image processing. The normal ISO range is 200-12,800, going up to ISO 102,400 at the top end of the expanded range.
God only knows what kind of photos it's going to turn out cranked to that ridiculous setting. Even if you aren't shooting anything with an ISO approaching the size of small lotto winnings, the lower level ISO settings, like around ISO 6400, should look even better than same setting on the D3. Nikon stressed that ISO 6400 and up to 12,800 would be "comfortable" to shoot at, so they are setting up some not-exactly-moderate expectations.
