Because This is my favorite mode I will express in more detail.
In portrait mode, as well as in chart mode, there is a choice of zoom from 1x to 3x, but it should be understood that up to 2.9x this will be a figure zoom. But in 3x, if the lighting allows the camera to switch to the TV. I don’t really like it, but what to do.
The quality of course 1x gives an excellent result, but you do not understand the focal length, not for portraits. 2x is already another matter, but the quality is not very good. Therefore, in the room I prefer to shoot in the range of 1.5-1.8 x, and on the street portraits of course only on TV.
And yes, I prefer to still shoot in chart mode, so that you can later change the degree of background blur.
camera question - is it possible to do portrait photos with x3 or x1 camera?
