The RED Helium 8K (approx. APS-H size sensor) just leapt to the top of the DXOMark charts with a score of 108.
DXOMark have tested the raw sensor output of the GH4. Raw stills have 12.8 stop dynamic range vs 11.7 stops on the 5D Mark III, illustrating just how far ahead almost everyone is on sensor performance over Canon.

These findings have rather taken me aback.
Not only is the Nikon D800’s video quality far better than the Nikon D4 and more detailed than the 5D Mark III, the low light performance of the raw sensor data is nip and tuck with the Nikon D4 despite having double the megapixel count.
Even more surprising is that the D800 just scored the number 1 position overall on DXOMark… out-performing a PhaseONE digital back!
Needless to say this camera is now on my radar.

DXOMark have begun doing for lenses the great work they did with camera sensors. That is to say comprehensive scientific rankings of outright performance plus (deep breath!) a break-down of results into more detailed areas, and that, erm, makes for some fascinating discoveries.
