It’s 19.6/5 as per DPR & Gerald Undone test (guest appearance)

Sony did what they had to do to update the aging a7RV without rocking the [Sony] boat.
The could have innovated and stepped up with new LCD screen, new body style, better video (open gate, internal raw, less crops, etc) but clearly they don't want to eat into the a1 II and a9 III segmentation.
Regardless, I'm not the target audience for this, I'm happy with my a7V.

Part of the confusion here may be due to video (which I thin Gerald is usually concerned with) and RAW images (which I think is what Duade tried to measure).

But it's a replacement for the a7rV. Other than a few people freaking out online over a new toy nobody expects an a7rVI to replace the a1 series.

Im speaking the utility of the camera and price. I didn't see anyone freaking out about that. You can get a nice mint A1 for low $3,000. It was a genuine question

As a birder that often crops alot the 66mp has me intrigued but yeah the readout speeds might cause me to stick with my old school A1. I skipped getting the A1 mark 2 because it didn't seem like much of an upgrade to me but 16 more megapixels to crop those birds with seems huge.

Sony says 16 stops of DR in mechanical shutter mode, same that they said for the A7V (from combining the two ISO gains), so the DR should look very close if not identical to what Photons to Photos has measured for the A7V.

That is a heck of a spec-sheet. What does this leave for the A1? I was an early adopter on the classic A1 and still absolutely adore that now "classic" camera, but this A7R6 really does tick all the boxes that I felt was lacking on the original A1...

I still don't think a confirmed number for the readout speed is out there. One of these numbers may be the correct one but people are just using things like A7RV being 1/10s (which isn't true in every mode).
I looked back at Kasson's testing for the A7RIV and I assume the A7RV was the same.
His testing found 1/10s when using Uncompressed RAW with Single shot.
But he got 1/20s using Lossy Compressed, ES and AF-C.
So if we apply Sony's 5.6x number to 1/20s then we would get 8.9ms which is fairly decent for birds.
That is a lot faster than if you do the math most reviews are doing of 1/10s x 5.6 only giving 17.8ms.
So until someone actually tests this camera ( @snapsy ) then we won't really know how fast it scans when in Lossy Compressed, AF-C which is where it matters anyways as that is how you get to 30FPS and would shoot fast action.

Your A1 still has the advantage of a fast sensor readout speed of 3.8ms, compared to the A7RVI at 19.6ms, so your A1 will produce noticeably less rolling shutter and virtually no distortion when shooting fast moving subjects using the electronic shutter. Also, your A1 does 120fps for AF calculations, wheres the A7RVI is half that at 60fps.

Those advantages you pointed out only really affect a very small niche in photography.

Small like pro sports and wildlife? You could make the same argument about 18 more megapixels. I'd rather have the advantage of a significantly faster clear rate. To me, it's the difference between using the electronic shutter all the time or using it more selectively.

I only compared new products, e.g., a1 II is $7000, but of course I can understand some different ways of thinking.
By freaking out I mean overenthusiastic. It may be part of the "sneaky" marketing.
I am also interested in the Claff data, but mostly at high ISO. I'm not quite convinced that the DG DR at low ISO always translates to better noise at high ISO. Noise matters so much to me because it has to be removed by the AI at high ISO.
If ISO 3200 in ES looks significantly worse than the a7rV, then I have no use for it. 10FPS makes the camera less appealing.

I interpreted the 5.6x that Sony stated as the pixel readout rate. So when you factor the resolution increase, the A7rV time of 100ms translates to 20ms on the a7rvi. I did see some tests that measured it.
I didn’t see any specific results for lossy compressed. That might be 10ms if it follows the pattern on the Rv.

I shot with the a7RV for years, my pet peeves were:
- EVF resolution when tracking in AF-C
- Rolling shutter performance.
- Color science was very good, but not exactly where I personally wanted it
- Ergonomics
I am very happy to see the EVF pixelization has been solved, and there seems to have been improvement to color and WB (jury is out until we can see RAWs, but I am hopeful). Ergs seem to be better with a larger grip, but I really wanted the slanted shutter button from the a1 II and a9 III, but I guess that is how Sony will differentiate from their tier 1 bodies.
Some early nitpicks:
- 1/8000 shutter only, regardless of mechanical or shutter?! Both Canon R5 II and Nikon Z8 (2 yrs old machines with stacked sensors) top out at 1/32K in e-shutter. This is not great if you like to shoot wide open during day time
- I think they could/should have improved on the back LCD quality. Showing portrait clients the back of your camera is less inspiring on a Sony for some reason.
It will be interesting to see where this sensor lands. How long before we get an a7CR II? Will they let Leica use the same sensor?
I won't be an early adopter of this, but man, there is a lot of temping stuff in this body.
