I with to fly a GH3/GH4. I know from doing research that the S800 with Zenmuse is pretty solid. However, are there other reliable gimbals that will fly a GH3/GH4, or my 5D for that matter? My impression has been that there are other gimbals but they are unreliable or tweaky, etc. Is the brushless "revolution" I thought I read about last year here?
