I have all kinds of sensor cleaning stuff (and procedures) in my kit, but i'm too scared to use them on my Scarlet sensor. I don't even dare to have a look at the sensor through my Visible Dust loupe. I change lenses Scarlet looking down, frantically and quick avoiding any dust to swirl in.
So, call me a dustophobe. ;-)
Now, i know of people who never check their Epic or Scarlet gate and change lenses all the time, not worrying too much about sensor dust.
IF there is any kind of contamination on the sensor, how does this show up in the actual picture - when shooting 4K? Any examples available?
