Canon should have given the G1X II a newer sensor.
that the sensor performance is reported to be the same or slightly worse than the G1X sensor is a bit disappointing of course.
the G1X II sensor is bigger than the sony RX100 sensor, yet shows worse results.
that can´t be explained with an old manufacturing process either.
as some have reported the powershot sensors are produced on a smaller litho process than the DSLR sensors.
i have yet to test the G1X II but from the specs and reports the sony A6000 looks more tempting... for less money too.
