Did you read the full review?
"The scores say no, but our measurements loudly say yes, this is the same sensor but it has been tuned differently:
Strangely, the lowest ISO available on the NEX C3 is a mere ISO 200, this limitation does not allow the user to take full advantage of the built characteristics of this sensor in Low-ISO.
Not being able to go further down than ISO 200 explains the difference in scores as far as dynamic range and color sensitivity are concerned."
Actually You're comparing a compact size camera with a DLSR ! You just forget to mention that The Sony a580 (which has also the same sensor) achieved 80 score ! What a pity!
