This doesnt help you but on the sony rx 100 you can definetly change iso while filming.I suggest look for a used. Sony cx500 or 550 if you need long zoom and manual adjustment.
well thanx but the goal is not to buy a real camera, but to have a great compact digicam to film , accepted by security ( I've other things to hide ... lol ) .
Anyway in intelligent mode auto and auto + I've discovered we can set the luminosity with the "down" button and it has effects on the video ! Not so bad ! I will try this at end of January on my next show . For exposure I'm now sure it's impossible .
Finally is there any option to change exposure for filming?
How it run setting the luminosity with down buttom?
