This is a VERY interesting platform given the image quality of the GH4 even after so much time since it's release... The GH line is powerful. Does anyone know of goof reviews etc where I could find more information regarding the GB603? A. I am interested in finding out how the GH4 interfaces with the flight platform (Tornado + GB603). Can you control focus, aperture, shutter, WB, start-stop? What is the video streaming quality? B. I am also interested in finding out if anyone has flow a recorder to get 4:2:2 10-bit 4K out if the GH4. C. Will Yuneec's business relationship with Panasonic pretty much guarantee compatibility with the GH5 when it comes out? D. Estimated flight time?
