A leaker has provided further details about the Vivo X100 Pro+ or Vivo X100 Ultra camera flagship, which is expected to be launched in 2024. Based on a prototype, the triple cam equipped with 4.3x optical zoom appears to be quite versatile and can apparently reach ridiculous sounding digital zoom-levels.
Pixel binning is the reason.
The caveat is that the software used to process all that data needs to be good.
Well, I fully agree with this article. There is one other good use of binning/supersampling though, and that is better chroma resolution relative to luma.
But even that won’t do much, with all the other shortcomings already present.
