A couple more observations shooting the K-3III & X-H1 side-by-side.
X-H1 with dual UHS-II slots shoots more frames/ bursts before filling the buffer, and clears the buffer significantly faster, than the K-3III with only one UHS-II slot. And to be honest, I got tired of shooting 5-shot bursts with the X-H1, and the buffer still wasn't full enough to slow or stop the shooting process. Significant advantage to the Fuji, and is something I need to think about with regard to airshows. (Both cameras using UHS-II V90 cards, both set to shoot RAW + jpeg medium. X-H1 set for RAW + jpeg to both cards. K-3III set for RAW to card 1, jpeg to card 2.)
The difference in what my eyes see in the viewfinders, and the way AF indications are implemented, make a big difference for me in shooting moving objects. In favor of the Fuji. Still subjects, no issues with Pentax. Other people who aren't having any issues with the viewfinder seem to be doing fine shooting action with the K-3III.
