I have a Sony RX100 that I use for video. When there is too much light the camera (that has not ND filter built in) starts raising the shutter speed and the outcome is a somewhat strobic footage.
For outdoor I have a filter with a variable ND control that I can change to keep the same shutter speed but I have not managed to find a solution underwater and for the boat rides (other than getting an M67 filter that will corrode and get ruined very quickly)
The camera goes to max f11 so I believe this is an issue that can be avoided with SLR but I have yet to find a solution
Has anybody experienced a similar problem?
