I am not expecting miracles, but I do expect a decent floating scene, lasting a minute or so. I too corresponded with the Chinese factory. I described the problem and they said to go with the default values. I felt like I had been given the bush off. Well, I know for a fact that there is a big difference in the weight between an A6300 and an A7Rii or A7Sii, all of which I have tried. I am wondering if the problem has more to do with shutter speed and what I am seeing is shudder? I have been shooting at 24pm and at a shutter speed of 60. Maybe I should drop my shutter speed. Also is it too much to expect to see good 4k video?
