The newly announced a9II follows the a7IV in being a modest update compared to the 2-3 years old a9. The sensor is pretty much the same (no global shutter, no 36mp, no multi-layer sensor,...), the speed is pretty much the same, the UI is pretty much the same,...
Certainly useful tweaks for actual photographers, but an evolution more than a revolution. The AF will certainly have progressed but Sony themselves are pretty low key about that.
I had the cash ready for the rumored game changer but probably won’t be spending it.
To me this marks the end of the romantic myth about the endless pace of progress Sony can deliver to the market. It remains a great day for Sony photographers but it sucks big time for Sony fan boys.
If anything, I believe that there must be some extremely relieved people at Canon HQ.
Cheers,
