The lack of an AA filter on the V3 is an obvious difference. The Sony 16 MP APS-C cameras seem to use a fairly strong AA filter.

AA filters are another factor, but the principle of higher pixel density is sound regardless of that, as you must well know.

One of the benefits of small pixels is the relaxed requirement for anti-aliasing filters. Eventually we will have sensors totally free of aliasing (maybe at something like 700MP on FF sensors)

It would be interesting to do a similar test vs the a7rvi.

Yes, I remember that thread. You'll see my comments in it. At the time, I was having trouble seeing a difference between 12MP and 24MP using the same lens. That discussion clued me to the idea that I wasn't shooting images with sufficient detail to easily observe the difference.
