Hi all,

Ive been recently considering to get a Sony camera.
Ive had the chance to run with A7 iii and A7R iii and it was so good.

So my question is can the APS-C A6400 come to compare with their full frame A7 line?
How much am i missing with the Value trade off.
I lean more towards portraiture side of photography.

I currently own a 27-70 E-mount Sigma lens which prompted me to invest in my own camera.
