- Two of the three subscores consider only ISO 100, but not everyone shoots at ISO 100 all the time
- Their 'Sports Score' is a total misnomer - low noise at high ISO coupled with poor AF or a slow frame rate is not good for Sports
I'll actually disagree, not with it being misnamed, but with it being irrelevant. Again, they are measuring only the sensor, so its probably quite true that in a body with a fast frame rate and good AF, the D800 sensor would be superior. That body just happens to not exist from Nikon, which is irrelevant for what DxO concerns itself with.
But you are right about "sports" being the wrong name. If they just called it their low-light score, then people would just be complaining about what type of noise they prefer. Especially Street or photojournalism would be more applicable than sports.
Because obviously a camera with that DR, decent ISO handling, shooting RAW, and the ability to shoot 60 fps at resolutions higher than what Canon and Nikons top end cameras do, is WAY better for sports in the theoretical.
