With the DxO site apparently busy with moving, I was wondering if there is any other site/organisation or whatsoever with objective measurements on those sensors? I wanna compare them to the Sony A7 III and A7R III but most sites dont have any info about this specificaly.

Thanks in advance!

Is there a reason you did not look at the DPR info?

Sorry for the late reply, not always alot time to answer, but very interesting reads, so thanks everyone for that!

I did actually have a look at the DPR scene info, and wow! That is such an incredibly usefull tool. Together with the ISO scores, it does really help to get some insight into it all. Not sure how to notice ' read noise though'... In any case I'm now just waiting for the new sony APS-C camera, and I'm probably buying that one. More than enough reasons to go for that one as long as the ISO score doesnt dissapoint.

What is an "ISO score"?

If you are talking about a metric like DxO "Low light Sports ISO" or whatever they call it, where they cite the highest ISO that meets an IQ standard, those are usually pretty bogus for gauging actual high-ISO performance. They are often meaningless measures of noise in the brighter tones of medium ISOs, and have almost nothing to do with real high-ISO performance, because they report relatively benign photon noise with much more weight than the very ugly read noise that haunts deep shadows and even brighter tones in truly high ISOs.

I have accepted to not take the DxO scores at their words, and I was basing myself on the photon scores. Those might also not be perfect, but I do like numbers. Could you recommend a place to look at numbers that take into account the more various types of serious underlying noise?
