You really didn't appreciate the lack of shadow detail in the images
you posted, did you? Just look how "muddy" the shadows seem.


I appreciate the amount of detail given the shallow depth of field and
very wide luminance range. How much difference would a larger sensor
have made? Hard to say because no comparable image is available.
Anything else is just speculation.


It's not pure speculation, John, it comes from examining a number of
images made under comparable conditions by the different sensor sized
cameras. Murky shadows, lacking in detail, can be typical of small-sensor
cameras, particularly where some noise reduction has been applied (even
with that turned down to the minimum). It's the manifestation of the
reduced dynamic range caused by the smaller well capacity, so it has a
well-understood physical explanation.

Yes, a direct comparison on a particular scene would be preferable.

Cheers,
David

It remains speculation unless the specific camera is tested against a
larger sensor under the same conditions. Call it "informed speculation"
if you like, but it's still speculation.

.... would be necessary to lift it above speculation.

So the fact that thrusting a butcher knife into your heart will kill
you is just "speculation" because it's only killed every other person
that's tried it, but not you?


Apples and oranges.

...Idiot


Self-deprecation suits you.
