I find DXOmark pretty much useless. Yes there is alot of info about dynamic range and stuff. However real-life performance is what matters the most. Is AF fast with my lenses, what does grain look like, is the shutter silent enough...
What most people seem to forget that sensor isnt everything.
Of course. I doubt anyone is claiming that the DxO measurements give you anything like the complete picture.
But there is a difference between not having the complete picture and not having any picture at all.
DxO gives you some objective data about the camera that you can work with, but you have to go beyond the scores to get at it or, at least, understand exactly how the scores are derived. It's up to you to decide how important the various things DxO measures are.
Dynamic range is a perfect example. The DxO numbers show that the dynamic range of the Nikons exceeds the Canons at low ISOs, but that the curves intersect at some point and, depending on which specific cameras are being compared, may wind up favoring the Canons beyond that point. Does that mean that Nikon is better than Canon or vice versa? It depends on what you need out of your camera. If dynamic range isn't important to you, then the dynamic range numbers can clearly be ignored. But if you're a landscaper trying to eke out every last bit of tonal detail to be found in the scene, you're probably going to want to know just what the camera you're considering is capable of in that respect and how it compares with other alternatives you're considering.
There's no substitute for real-world experience with a camera, but the problem is that even that is dependent upon the individual. You simply cannot take someone else's experience with a camera and presume that it applies to you. How you postprocess your shots, for instance, may differ greatly from how someone else does, and that matters when it comes to how the attributes of the camera will affect the end result.
In the end, it's better to have data that you don't end up using than it is to need data that you don't have. DxO provides data. Whether you use it or not, and how you use it if you choose to, is entirely up to you.
