I bought the OM4 a few weeks back and I'm ashamed to say that I can't get footage as smooth as the videos that I see. I know how the apps and controls work but I still see shakes. So I'm guessing it's how I actuall use them? Many tutorials do not teach this as they are more focused on the device features and their own footage. Is the "ninja walk" all there is to it? I have mild nerve damage on my arms so they shake a bit (just a little) when they are forced to stay up in the air for long, so how do I make it work? Any thoughts?
