I'm not aware of any unusual CA issues with the M9. Are you talking about the UV issues with the M8? Those were fixed for the M9, but unfortunately never fully fixed with the M8's... CA is largely an artifact of the lens, not the sensor, no? In any case, you can pick up a barely used (makes me weep with joy and sadness at the same time) M9 for about $3500 these days... It's the only reason why I'm even considering it. $7K for a body is insanity. I did manage to get to play with a preproduction X100S by a stroke of luck. I like it, but it's not really the shooting workflow I'm looking for. I have the OM-D for that.
