Hi Wolfgang,
A quote from my post, I think you missed that I turn off the AF after it has found infinity.
“I only have Canon L lenses, I auto focus (it’s constant infinity) in still mode, turn off the af then switch to video mode.”
The more I experiment (I did a quick test in a Cessna) the more I think it is slight vibration from the air flow. I keep out of the slipstream and inside as much as possible. I think I need to build some kind of deflector for the camera.
Like I said before it’s not unsharp like out of focus, just very fizzy looking, lacking in any kind of quality.
