karelderaat you need to bear in mind that imatest numbers are not absolute, they are relative to the resolution of the sensor (line widths per picture height). With an increase of resolution of the sensor the test score of a particular lens that is not out resolving the sensor will drop. Of course the amount of detail captured would be the same

 

OR is an increase in mp count gained at a cost in another aspect of sensor quality, resulting in blurring the theoretical gain in resolution away? That would be a very bad thing. 

Increased noise from smaller pixels - see sony a7s / nikon d4 etc have low resolution sensors (12MPix & 16MPix) but the best low light performance.

 

color casts and edge smearing also apply to sony 35mm sensors with wide angle lenses - eg a7r + voigtlander 15mm. Voigtlander have actually released a new version that solves the issue (with an increase in size) now.
