The way I see it is that they're doing what car manufacturers do. Honda may put a K20 engine in dozens of models but some have different compression ratios, VTEC profiles, turbos or naturally aspirated, and all are tuned differently. It's the same here. The same imager goes in, with a different filter, and optimize the performance for a specific set of goals. Just look at Sony's 20 MP 1" sensors. They're used in lots of different products with some features disabled or enabled. Like how the AX700 only has 14 MP actually usable.
Is because quadpixel arrays cant generate a more detailled image with an upscaler. Each "subpixel" has limited color information. This is what give us percieved contrast and detail in images
This is what they do. The 48 megapixels are binned down to 12 so the noise performance is the same as if the sensor actually had 12 megapixels. Functionally, it may as well be. The question is if the sensor is always going to operate in binning mode, why make it 48 megapixels in the first place? Typically binning would be used to give the user the option to trade noise for resolution, or to crop in by 2x without losing resolution (this is commonly done on phones.) But the Sony cameras never switch the sensor out of binning mode
@@VideoTechExplained It's probably easier to base -out- it on the 48 MP imager to reduce manufacturing cost. Tooling up for a bespoke sensor for a low volume product doesn't make much sense unless it's 95% already done. Chances are that they designed this sensor family to have a 12 MP version from the get go so that there weren't many compromises of adapting an existing design.

Sony has MP's to spare...the sensor kings.
So every photosite real size is about 4 microns?
lol they just do it so they can sell the a7r and a7 lines with no overlap. comes down to money
The a7R IV and V use a totally different sensor, though. So does the a1
okay but still only 1080p chroma
Couldn’t they also average the noise from each subpixel to end up with less noise per binned pixel?
Perhaps, but noise has already been solved with post processing now...not an issue like it was a few years ago.
