Hello, As a happy owner of a movi m5 using it with a 5d mIII. I am pretty exiting to see the new Sony fs5 and considering it as an upgrade. Now will the fs5 be compatible with the movi m5? The H x W will not be a problem. It is the lengthy depth of the camera that will cause the problem. (17,46 cm) Balancing it with a light prime lens could make this the ultimate camera to get for the m5. Thank you for your time and answers. Greetings from Belgium!
