p.3 #1 · The sensor read-out times on the A7Cxx cameras?
If you want to call it what it is, it's a 48mp quad bayer sensor used to produce 12mp files.
That is simply a fact.
Context matters. Sensor readout times is the title of this thread.
Comments were made comparing the A7SIII read out time and speculating on a 12mp stacked version.
So if the same configuration was used, it would be a 48mp quad bayer stacked sensor.
If a 12mp regular stacked bayer sensor was used, only 1/4 of the number of pixels would need to be read. If a 48mp quad bayer sensor was used, 48mp need to be read before binning occurs. I don't see how reading 4 times the pixels would not be slower.
Therefore it is relevant to this thread.

This is a stupid argument and I am going to end it. My position is that it should not be called a 48 pixel sensor unless those pixels can be used independently and produce 48 MP output and they can't. So, let's not fight about what to call it. Let's agree to disagree. You want to call it a 48 MP sensor. I do not. Sony does not, but you can call it what you want.
And context does matter. We are talking about sensor scan speed (i.e., sensor read out) and nobody knows what binning those four sensors into one pixel does to sensor scan speed. If you want to make claims about that I am all ears. Do the 48 individual sensors need to be read and binned before sensor read out, or is the binning done at the sensor level as they are read? Is the process parallel or serial? However it is done it is done very quickly because the sensor scan speed of this sensor is very fast. No, it isn't a stacked sensor, but I suspect--and this is just a speculation--that like a stacked sensor the binning of those sensors is done at the sensor level allowing that binning to happen very quickly just like the processing done at the sensor level in a stacked sensor is done at the sensor level allowing it to happen very quickly and if the binning is done at the sensor level increasing its speed then all the more reason to think of the sensor as a 12MP sensor. Yeah, Sony could have made it to produce 48MP output, but they didn't and part of the reason they didn't I suspect is to produce its very fast sensor scan speed and that fast sensor scan speed is not speculation.

You obviously don't understand what 'ending it' means.

I think I do. It means I will listen, but that was my last post making any claims about the sensor. You are free to comment more, of course, but I am not going to engage with your argument.
