Recently, I bought a Sony a7r IV. The main reason was for stock photography. The high resolution along with improved focusing and biggish buffer would allow me to make better people (and other) stock photos for my various stock endeavors. The Sony system has treated me well. I own two A7r II's for stock and other work, and two a6500's for event photography. The A7r II's aren't ideal for events for a couple reasons. The focus tracking is pretty good, but maybe not enough for fast paced people on stage. Another reason is that silent shooting is only available on single shot mode. And (admittedly a first world problem,) the files are much bigger than needed. Well, the last problem, too big files isn't an issue with the A7rIV if you use it in APS-c mode. The files are effectively the same size as the a6500: 24 mp. Focus with the IV is even faster and more effective than the very capable a6500. And with those smaller files, the IV has no problem with buffer overflow. So
