I think color issue at least in JPEG is established in dpreview GR3 review though color desaturation in RAW as ISO climbs up is not adequately addressed.

There's no unusual color desaturation as ISO climbs up. On the contrary, the GR III is quite good at keeping the color.

Premature color desaturation of GR3 RAW

Here is a sample at ISO 800 but color desaturation in RAW is noted even in base ISO or from ISO 200. It is subtle but it is there.

I strongly disagree with your assessment.

First, you're using the comparison widget which doesn't work properly. But let's ignore that for now.

Second - and most important - your selection is not meant to show color desaturation. Some things to note:

- if you compare the GR III at ISO 100 and ISO 800 (and higher) you'd notice how well it keeps the color. There's no noticeable desaturation; just the extra noise.

That's why I said premature color desaturation of GR3 RAW. And correct wording may be 'There seems to be no further noticeable desaturation; just the extra noise.'

Your "premature color desaturation" simply means that you don't have a base line. It simply means you cannot show any color degradation as ISO increases - because there isn't any.

When you compare GR3 RAW with its peer (for example D7200) RAW and GR3 RAW shows color desaturation at each ISO does it not mean anything?

- you instead are comparing different cameras, with different processing profiles (and a software that didn't yet support the GR III).

- even more, you are trying to be unfair by including full frame cameras.

I included Nikon D7200 which has same APS-C sensor

Same? Are you sure about that? Does it have the same Bayer color filter array? Does Adobe process the RAW files in exactly the same way?

Don't make things complex. It is a common sense to make things as simple as possible when you make an argument. Making things complex only makes things complicated and unsolvable.

with same MP count as that of GR3, same 24 MP but FF D610 and 36 MP FF D800. So GR3 vs. D7200 is a peer comparison and D610 for same MP count but to compare APS-C with FF and D800 for 24 MP APS-C vs. 36 MP FF. I think all meaningful comparisons they are, interesting comparisons at least.

Only to the point that you still fail to show this supposed issue, despite such an unfair and incorrect comparison.

Supposed issue? If you do not admit an issue I do not have to argue with you. It's a waste of time.

What you're describing is basically the Loch Ness monster - you say it's there but it just can't be seen.

The truth may be we differ in interpretation of fact. The fact is standing like a mountain. When you are blindfolded of course you cannot see whatever there is.

Curiously, when you are blindfolded you might see what isn't there.

I wear glasses not a blindfold. Isn’t it a paranoia to worry about something which is not real?
