Good they corrected the scarlet fever phenomenon, I was already aware of the rest of it.
The AF improvements are going to be an interesting topic. It probably rightly so got flak for not working as well straight out of the box (like Canon or something) and it's probably still like this.
I wish it didn't have those AF sensitivity settings etc. as I've no idea about how to optimise it and if you change this it is better for certain things and consequently worse for others... I've currently put this on the back burner while I learn other options first but I'd rather it did not require such customisation and then if you can save such separate AF custom settings as a customisation I'll lose the plot and probably not touch it.
Take into consideration I was a recent Pentax DSLR user who used it much like a film camera so I'm still kind of old school, proof being the S5ii has only been used in M mode BUT I love the top left drive dial and I've used the detection and tracking to get good results on first go with Mr/Mrs Cormorant bird.
Maybe we'll see updated reviews besides our own regarding the new firmware in relation to a sports camera? Realistically I'm not expecting Canon R6 ii AF performance but Panasonic should strive for it. As a stills photographer they have given me a brilliant video camera and they have really nailed this and I'm now using video whereas with Pentax it was pathetic.
I'm reiterating this as both sales people in the shop asked me why I chose S5ii over the Nikon Z6ii and both looked bemused when asking me did I do more video and I said "well probably only 30sec clips from a mountain summit or something". So the perception is still that they are better for video than photography but nowadays hybrid means hybrid and modern tech means both are possible. Leica will equally benefit from this too as in great AF stills and video i.e both.
If I think this then I'm sure Panasonic know this x100 and unlike the system I came from actually do listen to customers and want more customers. The S5ii could become their reputable focal point in FF for them and keep selling it for a few years especially if they continue to improve it via firmware and the great deals... £1629 for S5ii with 20-60 and 50mm lenses, but clearly they already know this.
Disclaimer: I could be full of crap to the above but at least it's wishful thinking, as long as they don't start making toy film cameras instead we're OK for future proofing
