I have started making timelapse videos, and record everything in RAW to ensure that I have maximum dynamic range available. I considered getting some form of mirrorless camera with an electronic shutter. Be that Canon, or some other make. I then found out that of course the electronic shutter options of most of the second hand cameras that would be available in my price range had speed limitations. Seems that it's only the higher shutter speeds that the electronic shutter option works at. So where I might want to run a timelapse through dawn or dusk, well no electronic shutter options at those slow speeds. When you might be shooting 3600 frames an hour, to make one minute of video, it would be nice to not have to use a mechanical shutter.
