GH4 GH4: Shutter Angle: Exposure Issues

I think very few Panasonic users shoot with a ND filter. Only some are pro users like in this forum. The others use full auto which fortunately avoids f22 but those shooting with S-mode drops to f22 and they never know why their videos are soft.

On this forum? Most people here are serious about their craft and have had "avoid auto" burned into their psyche.
 
Truth be told though, I think most pro users would love to not use ND filters at all. I'm sure there's some technical limitation, but if camera companies could make a sensor that allows for extremely low ISO settings (5-100) while shooting video, it would make life easier for all.
 
Does the current (newest) GH5 FW show exposure info to user when shooting video (not in phone app or in exif file).

f/22 on a micro four third sensor does not make any sense at all due to diffraction.

Also shows up any dust specks on the sensor (more correctly dust on the glass in front of the filter casting shadows onto the sensor) much more with smaller apertures. Dust is a big issue, something to be constantly on guard against. Never thought I'd spend £100 on a brush but the Arctic Butterfly is worth at least that much, works really well.

It's my understanding that as soon as you move away from the sensor's base ISO you start to compromise dynamic range, therefore very low ISO settings would not be the answer.

When the industry finally moves to 60P or higher there will be no need for ND filters. GH5 is one step in that route.

No, if you want any kind of shallow depth of field outdoors in the sun and want to maintain a 180 degree shutter, you will still need ND filters. Only lower iso sensitivity would get you there without ND's. Internal ND's are the next best thing. Maybe some kind of electronically variable ND filter in front of the lens, like an LCD panel, could do it. Something like this, but build it into the camera--

With 60P or higher we dont need to follow 180 degree rule. Also the high shutter speed stuttering is not very visible with soft background.

Maybe. There is no agreed upon aesthetic for rendering 60P motion other than live television. Most narrative work, even documentaries, wants to stand apart from such content. 180º shutter angle for 60P is still a great reference point.

Regardless, changing shutter speed to control light is not a good idea for motion work, it affects the feel of the motion. Period. That choice should be reserved for creative reasons if at all possible. You certainly do not want to be changing it mid-shot!
