I'm a RAW kind of guy but it's a preview. "Half frame" fanatics should
be ecstatic!

All you're comparing is JPG engines, which have so many variables that
with a few tweaks you could shift "better" from one camera to the
other in minutes. Show me the raw files and then we'll know. This is
for the curious, but really says nothing.

Only if the raw files aren't "cooked". Fuji are the latest culprit,
with raw files from X-trans sensor models showing less shot noise than
would be possible if quantum efficiency was 100%, kicking in at settings
above ISO 1600. In fact, raw data analysis shows exactly the same
amount of shot noise from ISO 1600 to ISO 6400.
