I went through the 52 RAW files from DPR again and extracted both the fullsize + regular embedded JPEG sizes along with the overall RAW file size. The total percentage of the filesize taken up by both the embedded JPEGs is shown in the export below:
It boggles my mind that Sony engineers would think this would be a good idea at all to waste so much space and CPU time. I bet this is one of the reasons that the Alpha 1 can't actually do the full 30 fps with tracking as shown in the Mark Galer review. It could only do 26.6 fps with tracking and you have to drop down to wide area - no tracking in order to do 30 fps. The CPU is wasting time creating full size JPEGs instead on AF! This is just so plain wrong and absolutely unnecessary for a sports camera! 5-20% of the Sony Alpha 1 RAW file is just a waste of space and time....Show more →
Sorry but you're making a lot of wrong statements, you don't know what you're talking about, and also you have a very destructive attitude here, and clearly not an open mind.
1) the A1 has 2 CPUs and Sony crew explained that 1 of them is doing AF + tracking + ... and the other CPU is doing compression + IO + interface + FTP ... so it means the AF is not being slowed down by the JPEG creation and it also means the CPU is not a bottleneck since it can do 30fps with raw+jpeg and more, there is just enough juice in that CPU.
That invalidates half of your post already.
2) So the RAWs take 50MB instead of 40MB because they contain a full jpeg inside, you know what? That's GREAT, why?
a) 20% increase is really not much at all when you think about it, instead of 4TB of data it will be 5TB, no big deal
b) decompressing JPEG is done in hardware whereas decoding RAWs takes a lot longer (think 100x longer, this is hardware vs software), therefore having an embedded JPEG allows for:
- the camera to display the full images much faster, no huge slowdown when you want to zoom in unlike previous models
- same for your computer and for the RAW software like LR or C1, well, once they support the new format
c) this means the overall workflow is accelerated, the culling will be much faster for one
That invalidates the other half of your post.
However, it would be nice to have some options to choose the quality of that embedded JPEG and to enable/disable it. But by default, it's a great feature.

Did we not give Tony Northrup a pounding for not using "all possible combinations" in his preview video of the Alpha 1 where he says he could not get 30 fps? Why the double standard for Mark Galer vs Tony Northrup on the exact same topic?
They are completely different. The Northrops eye candy click bait and Mark Galer provide substantive technical information on Sony cameras.

If you get your Alpha 1 CPU info from YouTube, well, the Sony live chat guy in YouTube named Mike doesn't even know that there are full sized JPEGs embedded in the Alpha 1 RAW files and still thinks it's only the small size. Trusting technical info from the marketing department of Sony on YouTube is as smart as looking up at a flock of birds with your mouth open.
And as I wrote before, the average size of the Alpha 1 compressed raw files is 57 MB, not 50 MB like you wrote. It is 28% larger on a per pixel basis compared to the per pixel value for the A9ii, not 20% like you wrote. This contributes to lower performance in the buffer, which is what matters, not your post processing where you can take ages.

Ah yes...great minds think alike...him and I would get along well complaining about all the little things these cameras lack. But I am happy that Sony has addressed a number of these little things.
After just watching that video, I'm a little disappointed that he says wake up time is no better and that when waking up the overlays still sort of come up one at a time and no faster. I had thought the new CPU would have improved those two things.
Couple more confirmation. Dan Watson at 59 Mins he says it's half the time of A7RIII. He doesn't have A9II.

Yes the way he sets it up in his reply to you is pretty much how I run my Sony cameras currently. My PSST is maxed out (I think the A1 lets you set it to never power save). I have a method of setting up the EVF/LCD display settings that allows the EVF to turn off very soon after taking your eye away and only wakes up the LCD for Playback and Menu. To shoot via the LCD I have a custom button to toggle over to it only when I'm going to shoot via the flip screen. I don't have much in the way of battery issues with my current setup so I will continue on with my setup when I get the A1. Sure it must drain battery faster than if I did use PSST but it isn't a problem for me.

I'd love to do this. Operate like a DSLR. Will dig into menus. If you can remember how you did, please post here. I'm sure it will be useful for others.
Camera 2 menu -> Page 7ish (depending on camera) ->DISP Button->Monitor-> Make sure 'Monitor Off' is a selected item. Then you can just hit disp until the monitor turns off, and the EVF will still only activate when it detects your eye is near it.
Credit Mark Smith for showing me that when I was down there ;-)

As buffalowolf said....in the "DISP Button" (page 7/11 of the Camera Settings 2 section on A9II) menu for Monitor I only select Histogram and Monitor OFF. I have my FINDER/MONITOR switching set to Auto. I then use the DISP button to toggle between Monitor OFF and Histogram. I toggle into Histogram when shooting via the LCD. Otherwise I leave it as Monitor OFF. When it is in Monitor OFF and you aren't triggering the EVF Auto sensor, if you hit Playback or Menu it brings that up on the LCD. Also if you aren't triggering the EVF sensor, and you just change a setting like ISO, Aperture, SS etc it shows just the bottom black bar on the LCD with the exposure settings and the setting you are changing but doesn't bring up the live view image.
So that is DSLR mode with a quick way (just hit DISP) to get into LV on the LCD when you want to use it to shoot from.

Amazon now showing Mar 9th for shipping, not sure if that includes all previous preorders
Yup. Every US store except B&H has revised ship date to March 9th, Sony says the snow storms slowed down their initial delivery to stores. B&H confirmed in a few places yesterday that they still think they will have their shipment to them on the 4th, and will start getting them out the 4th and 5th depending on when it gets to them..... we'll see.
Wow the tracking on that duck video is amazingly solid considering the backgrounds the duck flew past. Busy, far with transitions to sections busy close.
I don't think there is another camera that can do that as well. For sure not at 30 FPS and 50 mp.
