I would find it really strange that G12`s 1/1.7" sensor (with its 10 MP and an f/2.8-f/4.5 lens, and yes, I know 4.5 is at 140 mm equivalent) is giving a better image quality than a G5X`s 1" one (with its f/1.8-f/2.8 lens, and 20 MP). Maybe, but just huge maybe in a really good light (as G12 has a CCD sensor which some consider sharper), but as soon as shooting conditions get out of "ideal" zone, G5X`s light gathering abilities should win hands down (because of both the sensor size and lens speed).

That said, if you`re comparing both images at 100%, then I think you`re simply doing the wrong thing. One of the ideas of higher resolution cameras is not (just) to allow for bigger print sizes (or viewing at higher resolution screens) - while you can do that, of course (but usually without much noticeable improvement in quality), the biggest gain is in having a better image at the same (physical) size as before (but with more mega-pixels now, thus a possibility for more data/details, and a better image).

I can`t say I don`t know the feeling - coming from a 3.2 MP CCD camera (Canon A75) to a 12.1 MP CMOS one (Canon IXUS 220HS) I was shocked with the decrease in image quality... when looking both at 100% But what happened is that camera market made a shift in the meantime, blowing up mega-pixels and changing its philosophy - and yes, actually printing the same sized image was now at least the same, or usually better, with that important difference that shots which were impossible to make (because of difficult/missing light) with A75 were now more or less easily achievable with IXUS 220HS.

p.s.Ok, I re-read your post, and being a dSLR user, I guess you don`t need me to tell you about the stuff I previously wrote (I`ll leave it as it may come of some use to others)... But then, I must say that I`m really surprised by your disappointment - could you post some images (even better - RAW files), helping us to see where/why your expectations failed?

I`m interested because I have G7X (sharing the same sensor/lens combo with G5X), and I`m nothing short of impressed with it`s capabilities so far (and all the data inside the RAW file)... but yes, I understand that not everyone has the same needs/views

I don't think that the sensor is at issue with the G5X as outlined by the OP; it's the lens that's the problem.
