So, assuming the various reports are accurate, the sensor readout speed and the AF calculations per second explain why the A7RVI is not really a competitor for the A1 II. There is a vast difference between a readout of 19.6 or 20 msec and a readout of 3.8 msec. The former will get you rolling shutter and LED banding, the latter virtually absolves you of both. And twice the AF calculations per second will give the A1 II a very signfiicant advantage in getting sharp images of subjects in motion.
The 20 msec readout speed is really a disappointment. It makes the stacked sensor not really worth having, except for slow-moving or stationary subjects. And I would anticipate banding with LEDs.
This also makes me less eager for the A7CRII.
Did you actually think this camera would compete with the A1 for action? The fast sports or birds was never the target market of the A7r series and this version of it still is not. High pixel count, image quality and dynamic range is where the A7r cameras shine and I’m sure this will be enhanced upon with the A7r6.
People needing to shoot high speed sports or birds already have the A1 and A9 lines to choose from.
I of course didn't have an opinion about whether the A7R6 would compete with the A1/A1II until the specs were out. But the rumors about a stacked sensor made it a possibility, one which hasn't been realized.
And it's a misunderstanding to think that a fast stacked sensor is only valuable for birds and sports. I often want to shoot with a silent shutter under LED lights. That is only possible with a fast stacked sensor. This is also one of several reasons why the A1/A1II and the A9III are so popular with event and wedding shooters as well as documentarians, who don't have a bird or a ball in sight.
Slow readout sensors under electronic shutter also distort faces and bodies that are in even moderate motion, especially when they are close to the lens. A fast readout stacked sensor doesn't have that problem.
