Credit.. Alister Chapman.. just read this .. and its the first time I have ever seen someone make this comparison /explanation of the ever discussed "Arri look -Sony look".. makes sense to me.. and typical of the Japanese mind set for everything to be incredibly accurate .. over the actual greater goal.. to make a video camera that produces nice images..
"Arri's colour gamut is very limited compared to Sony's. The Alexa sensor has nowhere near the gamut of the F55 or Venice. But that is what gives the Arri cameras their out of the box look. One of Sony's problems has always been the effort to produce an accurate large gamut image rather than a pleasing image. Point a Sony at almost any test chart and you will see very few problems in the colorimetry. But often accurate isn't as pleasing to look at as more artistically adjusted colors. "
