I totally agree. But my comment was regarding other comments for AF speed in sport. In sport the cropping ability is very inportant.

Do you have a reference for this? I did some digging (not much) and saw some comments that sensor readout speed doesn't matter, since the AF system only needs to read the phase detect points.

I believe it does help, but Sony cameras with slower readout speeds already had excellent autofocus. So I’d say the autofocus algorithms and processor speed are likely more important factors.

15 stops with DR-boost is nice, but will an impact on shutterspeed (for video). So I would turn it mostly off.
(Not that I would buy this year de S1ii).

DR boost just means it's recording a full 14-bit raw. At least, on the S1RII anyway. But yes, it does slow down the frame rate a little, and cannot be enabled for 40 fps shooting.
<edit> I realize now you are talking about video. 12-bit readout does help reduce rolling shutter, if I recall correctly.

No, that's DR Expansion. And that's what the S1RII does. DR boost is something different. With DR boost it reads one pixel twice simultaneously with a higher and a lower circuit so you gain about one stop of DR. That's what the GH7 does and it's probably the most exciting news about the S1RII, if true.

Got it, thanks. But I think you mean it being exciting if it's in the S1II, not the S1RII? I searched the S1RII manual for the word "boost" and it only appears in the context of I.S. and Live View.

The S1RII doesn't have DR boost. It only has DR Expansion.
Off course it would be exciting if it would be in the S1RII, but it isn't.
Edit: I just realized my typo. I meant S1II, not S1Rii. Sorry.

The Sigma 50-600, 500, and 300-600 all have updated, faster AF motors. Presumably if Panasonic ever gets around to releasing their telezoom that has been on the roadmap for years, it will have fast AF as well. At least, we can hope. Sigma really ought to release updated versions of the 100-400 & 150-600 with the new motors. Now that we have the S1RII & S1II, perhaps they will.
Now, should Panasonic release some fast (and expensive) tele primes to compete with Nikon et al? That doesn't make sense to me until they release a true professional grade sports cam (hires fully stacked sensor, large buffer, a competitive AF system, etc). Of course, the Sigma CEO said he would like to release such a camera, but that was far from a commitment.
You do have to wonder if it makes sense for Panasonic to do battle with Canon/Sony/Nikon at that level. Perhaps it will if they manage to bring newer, younger shooters into L-mount, and then want to give them an eventual path to pro-level bodies. But as I understand it, most existing professionals don't switch systems very often, let alone bodies. So while the upgrade path might make sense eventually, I'm not sure just going for it right now and doing a head-to-head competition in that sub-market makes sense.
Having said all that, if Panasonic made a Z8 competitor in a few years, I could see myself buying it, presuming I end up enjoying sports/wildlife sufficiently.

I'll also say that it makes more sense for Sigma to go after the specialty long lenses - rather than Panasonic - since they can amortize the costs over both E mount and L mount (and, arguably Z mount, now that the E2Z adapters are out there). And - surprise - that's what we see happening.
