Also the G1X is much more expensive and larger. It's not fair to compare that to these.
The RX100 a much better comparison due to its size and price. Some argue that it lacks enough features that it should bepriced similarly to an XZ-2...having owned a RX-100 the IQ more than makes up for it. Of course tthat's one man's opinion
The x20 sensor is larger, but not by a huge margin. It's closer to the 1/1.7 than it is to the larger ones. At least as performance goes. It's more of a gimmick because it's really still a small sensor. On top of that, everyone thinks the 2/3 sensor is something new and revolutionary, not remembering all the cams of the past that had one.
Regardless, the G1x is a valid comparison. Everyone keeps establishing arbitrary parameters to try and make superior performing cams somehow not comparable.
