Hi, I am looking for some help in setting up and or information on wether or not the A7RIII can be set up to shoot in complete silence. I work on TV Sets and any kind of noise is not an option. i have turned silent shooting on, but there still seems to be a feint district click when I press the shutter. I could swear at some point during my testing yesterday I had achieved silence but then I either turned something else on (or off) in the menus and have not been able to replicate since. Any thoughts or advise welcome. Cheers.
