The 61MP of the A7RIV is not something to covet...

All other factors ignored (and sometimes there are other factors) going from 45 MP to 90 MP should increase sensor resolution tested in isolation by 42% (square root of 2).

Image resolution is made up from a percentage of lens resolution tested in isolation and a percentage of sensor resolution tested in isolation.

45 to 61 MP is an increase of 33% in potential sensor resolution - measured in isolation. While each lens and body combination needs be tested to get an exact measure of image resolution - a reasonable expectation is an average increase of 16.5% in image resolution.

To me a 16.5% average increase in image resolution for some types of photography can be worth having.

In lots of ways good photography is much more about how equipment is used rather than anything else.
