I think at the current prices everyone should just buy the 300PF , it's under 900 these days. I'm trying to resist the 500pf , but I already own the Fuji 150-600 , and the 500 with a TC to get the equivalent reach is also at F8 and I doubt the AF is as fast. My experience with the fringer is it's great on the XH2s but not nearly as snappy on the X-T5, the 150-600 focuses much faster and smoother.
