The sensor will be the 1/1.33" Samsung Bright HM1 - the very same seen in the Galaxy S20 Ultra. The additional laser focus sensor will assist the main camera, instead of having a static ToF sensor that analyzes the foreground and background.
The sensor behind the ultrawide-angle lens will be a 12MP ISOCELL Fast 2L3, which is 1/2.55” in size and comes with PDAF. According to the leakster, there will also be a periscope telephoto lens, but it have a 13MP Samsung Slim 3M5 - official numbers say it is 1/3”, while Universe Ice suggests it is 1/3.4”. With the smaller sensor compared to the Galaxy S20 Ultra the zoom will be limited to 50X - Samsung won’t pursue the 100X benchmark anymore.
