You're assuming that the Panasonic is a Sony sensor while the Sony IS a larger Sony sensor. What does Pentax Q gotta do with this? Can't really brain
Anyway, my previous post did say that in worse case scenario, the RX100's sensor only 1 stop advantage over the Panny.
As a whole, coupled with the brighter Panny lens, LX7 may have up to 1 stop advantage.
Then again, smaller sensor still smaller sensor when it comes to base ISO "look"
Besides, only when got good RAW support then only know.
Thanks. Wonder how the NR cleans up at darker scenes.
Yes, we need to wait for RAW support in LR than comparing both will be easy. I also hope dxomark can give the score earlier but they don't even have OM-D score out yet. They are crawling like turtle. At this time if one is considering buying either, then we need to put in some guesswork.
Pentax Q sensor is made by Sony. It is half the size of LX7 and yet outperformed other 1/1.7" sensor. Size matter, technology (Sony vs Canon vs Panasonic) also matter. The LX7 is not 100% confirm Sony sensor but it is 100% confirm not a Panasonic sensor. It can be Canon but never hear Canon sell their sensor to other manufacturer. It can be Aptina. It can be Sony (the biggest and largest sensor maker).
Base ISO look is not the case also. LX7 base ISO is 80, Sony is 125. If Sony sensor is 1 stop better, you have a 1/3 step differences in base ISO "look" only. ISO expansion are not on chip ISO but "post processed" ISO.
If RX100 is 1 stop better in sensor, a shot made at ISO800 f1.8 can be made at ISO500 f1.4, meaning RX100 is 1/3 step better only. This apply to the wide end. If it is the long end, the LX7 gain 2 stop advantage in lens but lose out 1 stop in sensor so nett 1 stop advantage!
And remember at 28mm of RX100, it is f1.8, at just 1mm more at 29mm is is already f2! At 35mm it is already f2.8.

Focal length 28 29 32 34 43 53 66 81 94
Max aperture F1.8 F2 F2.2 F2.8 F3.2 F3.5 F4 F4.5 F4.9
On the other hand, you can still shoot at f1.7 at 35mm of LX7
And RX100 is not sharp at the corners wide open. LX7 is ultra sharp. [of course if shoot for web only corners doesn't matter]
If you compare LX7 with system cameras with f3.5-5.6 kit lens, you will be surprise that LX7 can even beat them on paper.
I did my homework for one whole week.

Hope I can help you to see.
