Some odd decisions by Samsung.  The Ultra has some great camera hardware specs but the S20/S20+ don't have a true telephoto lens.  This Telephoto camera is actually 28mm equivalent vs the 26mm equivalent from the wide angle camera.  So the 3x telephoto is just a crop from the 1/1.7" sensor.  This was basically done to support 8k as the "telephoto camera" has 64mp to support the 8k and cropping.  The 1/1.7" wide angle camera has 12mp so 8k is not possible.  The S20/S20+ are really just dual camera phones (Wide and Ultrawide).

Here are the camera specs for the Ultra. Too bad this is only available with the mini-tablet sized phone.

Focal length equivalents:
13mm
26mm
102mm

Sensor sizes:
1/2.55“
1/1.33“
1/2"

Apertures:
F2.2
F1.8
F3.5

Yes, the telephoto module choice is indeed baffling. Also the 8K mode features a severe crop and should not a be a standout promoted feature, this is just there for bragging rights.

Ultra seems promising, but I need a reliable review before getting all excited. All in all there are still so many unknowns to the true performance of these photo modules.

So just digital zoom and no periscope lens on the lower-end models?

Correct.  The "TelePhoto Camera" has a 28mm equivalent FOV based on a 1/1.7" 64mp sensor.  So yes you can crop it to 12mp but the pixels will have a lot of noise.  That is why I consider the lower-end models as having only dual cameras (wide and Ultra-wide) even though there are 3 camera modules.

Preordered S20 Ultra, should be enough as travel cam/daily cam for me and nice 8K B cam to R5.

 

The DoF should be similar to APS-C on F4 for the wide angle, quite a bit nicer than F6.3 on normal smart phones.

 

Xiaomi Note 10 Pro is much cheaper for the price but there is something iffy about their software and UI in general and of course the security.
