resolution - Why does a newer camera get lower score for a specific lens than an older one on dxomark?


I was looking around on DxOMark and found discrepancy in sharpness scores which seems very weird.



The lens Olympus M. Zuiko Digital ED 12mm f2.0 has a sharpness score of "10 P-Mpix" when mounted on a E-PL5, while for the newer E-PL7 it is only 5 P-Mpix.


How can a newer camera get a score which is so much lower than an old camera for the same lens? Shouldn't the sensor be better?


Seems the result is similar for other lenses when tested on these cameras.


Can I really be sure, if I buy a camera which is supposed to be good but has not been tested yet at DxOMark, that it actually is not much worse than the previous versions?
