Nikon D300S

Low LightDynamic Range
Dynamic Range (7.34)
The D300S starts out with a strong 7.35-stop dynamic range at ISO 200, but it falls off fairly quickly at ISO settings above 400, resulting in a mediocre overall score in this section. At ISO 800, for example, the D300S is down to a dynamic range of 5.25, where the Canon 7D still offers 6.68 stops.
We test dynamic range by shooting a 20-section Kodak stepchart at a constant light level, across the range of standard ISO settings. The individual test shots are analyzed using Imatest software, and the results are then combined to produce an overall performance profile.
As shown in the chart below, where wider bars indicate a greater ability to maintain detail in both light and dark areas, the Nikon D300S performs well at ISO 200 and 400, but dynamic range drops off significantly from that point on. More on how we test dynamic range.
Looking at the dynamic range performance for each of our comparison cameras when shooting at ISO 200, all but the Micro Four Thirds-based Panasonic are roughly equivalent, with the Canon 7D offering a slightly more generous range.
When the full ISO range is taken into account, the Nikon D300S trails the other tested cameras in dynamic range, while the Canon 7D shows considerable strength.
