dynamic range - dxomarks and dpreview do not give he same resuts

DR gets more narrow when you add the ISO number and the true amount of noise in shadows is difficult to measure - it is different kind of noise in different cameras... sometimes more irritating. Numbers can look good , but not the image...

And it is not always clear that the other qualities of the image are ok if DR is "better". The final image - a huge photograph - printed on high quality "art" paper with a premium printer should be the final criteria. Not a measurement of a sensor output. That tech. information possibly helps when you are looking for the "best"DR - camera - if you had that in mind.

If you are looking for a camera for serious photography and you really need images with wide DR and well preserved highlights, you should check the new Fuji X-E1 - and how it produces very HDR JPEG images.

The other possibility is to look at modern FF cameras like Canon 6D. Are they so much better with their DR/noise/high ISO capability that it is worth the price... a difficult question. There is probably a good numeric answer to Your question somewhere in some test - keep looking.

Is this just technical curiosity or a real need to get good photographs?
