Yeah, the exit pupils of the X100, DP1, RX-1, etc. are still relatively far from the sensor, although it seems that Sony didn't optimize things as much as they could have, considering the RX-1 has a fixed lens and it is not THAT wide at 35mm. It certainly doesn't bode well for those wanting a FF NEX to use with M lenses, if Sony can't even nail the color shift thing with the RX-1.The glass gets very close to the sensor. this does however not mean, just like with the sigma dp1 and dp2, that the exit pupil, in optical sense, is close to the sensor. My impression was that these lenses are build this way, close to the sensor, almost covering it, to delivers parallel rays of light to the sensor, to improve the quality. especially the Sigma sensor is, as I understand it, sensitive for this.
and is it not so that the color shift here occurs form one side to the other? In that case nothing to do with the lens, at least not on its own. and flash seems to cure it, once again suggesting it is not just the lens.
p.s. here's a little bit of insight as to why color shift can be asymmetrical: Sony NEX-C3 first impressions - FM Forums
