GH4, G9, RX10 IV comparison at ISO 6400

- you are not really comparing sensors but jpeg engines

Technically it is both since the jpeg engine uses the output from the sensor.  I purposefully used jpeg as 95% of the time I do not use RAW.

- even on an ipad without opening or zooming in the gallery, the G9 looks slighly better

- how you display the results matters a lot. For example, I can barely see any difference between a well processed D810 file and a GH4 file, both at 3200 identical conditions and settings, when I dispkay the full images on a 55-inch 4K TV in my livingroom.

Yes, this is why I mentioned on the 60" HDTV.  It is a common viewing mode for my family in which we will do slideshows.  It does tend to be the harshest as in print and on a laptop the smaller size helps.

You have a valid point though as in, the difference is never as huge between formats as some may have you believe, and if your not pixel peep raw files at 100%. It is the same with m43 vs bigger formats.

Yes.  However, I also recently tried the A7III in crop mode.  This one was a clear winner as 6400 ISO was fairly clean and even 12800 was equivalent or better.  The problem is they do not yet have the lens I want in the size I want.  I was hoping the G9 would be an improvement that would get me 1/2 way there given the gear I already own.  However, it wasn't.  I can say I look forward to Sony releasing an APSC camera with the latest sensor or maybe the A7RIII dropping in price such that it could be used in crop mode (its a little bit beyond my budget right now).
