Great action sequences. The camera doesn't appeal to what I want, but its impressive to see the technology working so well and sounds like a pleasure to shoot with. Thanks for providing a field report.

I am probably not the best person to ask about that because I never noticed any reset in the EVF on the A1 - I use 240p on the A1.
Anytime you lift off the shutter on the A1 (or any other Sony camera) you will see the image jump ahead to the live feed. The faster the sensor read the less this is noticeable so the A1 is the least noticeable of all the cameras (up until the A9III). Canon R3 does this much worse than A1...R5 worse so (due to non-stacked sensor). The only camera I've shot to date that does away with this is the Z9/Z8. Based on Sony's marketing I think the A9III probably eliminates this also. Is this a big deal in shooting the A1?....no, not really....but it would be nice to finally get rid of it.
The only jump I have noticed is the IS reset. Do you see this when using 240p as well ?
If it jumps ahead to live feed then it must be behind so subject would be heading out the front of the frame. And there I was thinking I am just not so good at panning
With the a6700 you have to shoot using H to get realtime EVF view.
I learned something new today. DxO PL7 seems to rely on the optics modules for some sharpening - someone pointed out that the low ISO images in particular looked a bit oof. I restarted DxO and they seem to be looking a bit better now.
If anyone is interested I created a python script to batch modify the A9M3 files to A9M2 files so DxO PL will process them normally. The optics modules failed to load initially but I thought I could just ignore them - a bit surprising that they have lens specific sharpening that gets applied.
I can't see any difference in how the EVF works compared to the A1. It still drops quality of the live view feed sometimes and this can even be caused by your shutter speed and the feed is effected when you shoot a burst. Frame rate may also change while shooting bursts.
How this works is actually not trivial, there are up to 3 streams that needs to be read at the same time while shooting: live view, autofocus data and image data. Live view may sometimes be based on the image stream while bursting but not always (for instance if you shoot 10fps the live view stream still retains FPS, on the other hand if you shoot slow exposures then suddenly the exposure time and frame rate for live view becomes the same as for the images so then both are most likely from image stream).
It sounds like what Nikon does is place priority on the live view feed. That limits timing and bandwidth for the other streams and can potentionally be part of the reason it is limited to 20fps. If it has just started to read a live view frame it would have to wait until that is complete before it can start to expose the image for instance.
Sony on the other hand seem to prioritize shooting images over the quality of live view, in the A9III there is even an option to insert a black frame in the live view feed when starting to shoot a burst in order to reduce shutter lag
As long as it doesn't get in the way and hides what happens from me I personally think Sony probably makes the best choice here.

The reason DXO has arguably the best sharpening algorithms and lens correction is because they are lens specific and lots of manual labor goes into their creation - that is why there is sometimes a ridiculously long wait for profiles to materialize depending on product availability. More generic profiles like what Adobe offers are available almost right away for new products.
DXO's sharpening is proportionate to the lens' sharpness falloff from center to the edges, which is why it has to be lens specific. For example on a cheaper lens, sharpening is applied more aggressively as you move out from the center of the frame compared to an exotic prime where there is barely any sharpness falloff as you move out from the center of the image. Every other program applies sharpening either globally, or at least not proportionately though the frame.
DXO actually builds an all new RAW file from the ground up if you are using their RAW converter or Pure RAW - that is how they get the NR so perfect and is part of the reason why it doesn't have blotchy NR, artificing, or edge detection issues like Topaz is famous for, particularly with fine details like stray hairs or fine feather detail. It is not completely flawless but the reason it works as well as it does is also the reason why sometimes it takes them forever to release profiles for new equipment.

I took careful note today while shooting swallows and I can see no difference when shooting regardless of what buttons get pressed. Everything seems completely smooth, no stuttering, jumps or anything else before, during and after pressing the shutter button.
I shoot some sports but the A9II and A1 work fine for me. The global shutter does have me considering the A9III for strobe work. New or used there doesn't seem to be a strong market for the camera.
Spent a few hours out shooting with the A9III yesterday, trying to decide if the camera is for me. I'll have a few words and a few more images in a day or so.
