its hybrid, and the IQ is not great at all, as shown, or is it also out of focus. Your own photos of the tree showed very poor jpeg processing (smeary and waxy) as mentioned by numerous others.

From the main camera,

yes. Not from the telephoto camera

mmm, here's a 100% crop from the 108 mp jpeg file from another thread on the S20 Ultra, if you are happy with this, great for you, I know I wont be...

I've trimmed and highlighted this so your amazingly short attention span and inherent illiteracy can (hopefully) follow it.

oooh, such harshness... your 'inherent illiteracy' chirp is quite funny, coming from you! And you think the telephoto lens will miraculously use different jpeg processing to the other lenses...

It uses a Sony sensor instead of a Samsung sensor. It doesn't have pixel binning. So, yes.

but the Samsung processing algorithms will be the same.

if you look at the crops you'll see the processing is the same.

Nope.

You must be speaking loosely. Two processings from different source code are at best similiar in many cases but definitely are not exactly the same. Comparing two sets of different source code will not be exactly the same unless are identical which more than likely they not the identical in this case. Similar to your eye Jostian the cases may be. If you speak precisely how can they be the same?

as per any phone that has more than one camera (wide, UW and tele) the jpeg processing is the same in terms of jpeg IQ produced, you dont get different processing across different lenses in terms of jpeg IQ produced.

Obviously the code will be different as the different sensors have different specs etc.

I agree with part of what you say. The JPEG  Image Compression Codec algorithm  is a standard that the same for all cameras in a smartphone however the JPEG IQ being discussed the quality of the JPEG file generated by the phoone which is the result of an image processing pipeline including the CODEC as one of the final steps before saving the file.   This output differes from a raw file output in the image processing pipeline incorported before the JPEG CODEC step on the sensed image.  Some of this pipeline of "corrections" may be internal to the sensor chip  included in the raw file data but most of the severe corrections are done in software and only included in the JPEG file.  These severe corrections are dependent in part on the sensor chip and lens in use.   The JPEG file aberations IQ will vary to some degree for the different cameras in the S20 despite the same software codeset being used for all camera the parameters and performance for each camera will change the IQ for each camera.  The JPEG IQ will vary with the cameras in the S20 but there will be common IQ issues across all cameras as well since they do share the same  software code set just not the same sensor and lens parameters..
