Samsung really first they announced they are removing the charger from the box and now you put a less impressive camera in the note ultra and who knows for a higher price. Make right lower the price of the phone.

Nrlastest, 25 Jul 2020So...Samsung...another failSamsung isn't even trying nowadays. Now, they just release phones and price it high.

Nrlastest, 25 Jul 2020So...Samsung...another failI dont think so. First if it true that it will not have PDAF (Which I think 100% is not true) it will still be replaced by the Laser Autofocus.
And Higher MP doesn't mean better pictures. So even if they get rid of the 48MP periscope. The 13MP will produce the same quality. Actually, I think it will be better because the 48MP from the S20U is capable of 4x Zoom with 0.8 micro pixel. While the Note20U is capable of a farther 5x Zoom with a bigger 1.0 micron pixel. Also, it will be better in low light conditions because of the brighter f/3.0 aperture (Vs. f/3.5 S20U)

AnonD-909757, 25 Jul 2020Well ACTUALLY : With (S/A)/R for (Size/Aperture)/Resolutio... moreYou're correct

Anonymous, 25 Jul 2020The 48 is tetracell, not bayer. Always working at 12MP. I checked online and Tetracell is Samsung's name for quad bayer.

It is 1/3.4", not 1/3.6".
1/2" = about 30mm2
1/3.4" = about 13mm2

But yes, it would capture more l... moreOh, I tried to figure it out by myself without thinking too much about it, I wasn't sure it would work, though it still gave the difference between the two, what is the accurate calculation for that ?
Also, if the first lens already focus down before smaller zoom lenses magnify it, I guess it would allow for a longer focus length to lenses ratio, but I don't know what is best for telephoto though, a longer or shorter FL ?

But yes, it would capture more light per time per pixel. It would also capture more light per time per object, if the focal length is still 19mm.

"Using the same lens but losing the 2x from the sensor brings us to 50x zoom."
No, Quad Bayer sensors capture much less detail than Bayer sensors and also produce artifacts. If the lens is sharp and if the focal length is still 19mm, you should get better image quality, if you take photos from distant objects.

Well ACTUALLY :
With (S/A)/R for (Size/Aperture)/Resolution
((1/2)/3.5)/48 = 0,002 976
While :
((1/3.6)/3)/12 = 0,007 716
Meaning that despite the lower resolution, the sensor have bigger pixels, which mean it will collect more light per pixel, ESPECIALLY with a larger aperture, meaning that this sensor will be able to gather more RAW details and require less software enhancement than the 48MP.
Also I guess they took a smaller sensor to get a bigger aperture to sensor size ratio which could help having a better focal distance and having a better control over optical zoom while providing more light per pixels by focusing the light on a smaller surface.
So actually it make sense, mainly considering that with the 4 time binning the picture would be outputted as 12MP anyway and binning isn't a magical thing and a good hardware can do better.
So, literally, if they have a good sensor, with really nice light sensitivity, the zoom quality could be actually improved for both optical and numeric.
I'd admit though, I am not an expert in photography, so if anyone with better knowledge notice I said something stupid, don't hesitate to correct me !

The change is to make the cooktop smaller.
