Hi all, been having trouble with a firmware update. On my a7iv, going from 3.1 to the latest 5.1. So I've heard about doing a factory reset, is it easy and what do I lose?
As an added bonus yesterday whilst trying to do the update. I've now got another problem my shutter button isn't working properly. Any help gratefully appreciated.
I only bought the camera in October, having had an early a7 ver 1 previously for many years.
