I think these reviews do not make a fair adjustment for price. If you sell an expensive camera it has to be fully featured to justify its price.
Lots of less expensive cameras get marked down based on missing features. Oh, but its several $$$ cheaper.
It doesn't seem fair lots of the time.
The Rx100 IV certainly seems to be about as good as you can get for a one inch sensor but you are paying for it literally.
At circa US$1000 I'd say it is a fair price only. Definitely not staggering value for money.
