Agreed Mooncatt.
I spent a lot of money on lenses when I had my DSLR. Including 4 macro lenses over the years.
I'm not expecting the quality of a DSLR of course, but...
One Plus 8
Realme
Redmi
Oppo
and others.
I believe even the Galaxy M31 and A71 have a dedicated macro mode from what I read.
Just surprising the with the S20 series, Samsung chose not to include it.
It gives decent macro using x3 zoom in 3:4 mode (until you examine the images closely).
Maybe the engineers will bring out an update which does it on the S20 range. I live in hope!
