Una pregunta, y perdon por el medio offtopic... Sobre la "comparación" de la camara del XZ2 y el Lumia, y lo pongo entre comillas, porque pone que esta incluso por debajo del S4, el 1020.
Donde se puede ver este tipo de test, con fotos? cuales eran sus criterios? Es que me parece increible que Sony daba un procesado MALISIMO (superado por samsung montando lo mismo) y el XZ1 no solo desbanca al lumia 1020 por varios puestos si no que el XZ2 lo hace con el 808 (cuando yo creía que el 808 fue desbancado por el 1020)
No lo entiendo :S

La forma de evaluar se explica aquí (copy paste a un chico de Xperia blog)
No, they are not biased. It is you who just don't understand their measurements in assessing image quality, in case you don't know their industry standard test consists of taking 450-500+ pictures both in studio and in real life conditions. And they assess cameraphones in 8MP equivalent values, not in full resolution that one particular smartphone has.
Most of the pixel peepers only count noise levels, texture preservation, and sometimes artifacts in assessing image quality. And yes, 808 is better than Z2 in those regards, beating it with scores of 84 and 88 whereas Z2 has a score of 83 and 84. And 808 also scores far greater than Z2 in terms of image artifact with a score of 89 whereas Z2 only has a score of 68. And if you assess a image quality based on those 3 factors alone, then yes 808 is superior to Z2.
But in terms of exposure and autofocus, 808 loses badly to Z2.. (78 vs 88) and (73 vs 84) and those factors make 808 overall image quality is the same as Z2.
Also that overall rating represents a combination of photo score and video score.. And see for yourself, 808's video capability is inferior to Z2.
And here is their measurements to overall score =(overall photo score * 2/3) + (overall video score * 1/3)
Z2: (81*2/3) + (73*1/3) = 79.09 -> 79
808: (81*2/3) + (68*1/3) = 77.39 -> 77
Hopefully that clears up your suspicions.
