My NEX-7 has 24 MP, and the better lenses (most notably the Carl Zeiss) will
fill it with 24 MP of image - an APS-C size sensor. The RX10 and RX100-II 1" 20
MP sensor is BSI (backside illuminated) which makes a very significant
signal-to-noise ratio improvement over non-BSI sensors of the same size. The
other common issue with small(er) sensors is having a lens with sufficient
resolving power for the sensor pixel pitch. Stating the obvious, having a
sensor with a googolplex of pixels does no good if the lens is only capable of
delivering a googol of "information" to be recorded by it. The RX10 Zeiss
Vario-Sonnar has the resolving power to fill the sensor with more than 20MP of
data; i.e. the sensor is the limiting factor, not the lens.
