Class 480 is 480Mbs at 24/25/30.. and 960 at 50/60.. Yes fs7 doesn't have 480 (yet?).. I guess the idea was if you want 16 bit you add the A7.. it fits on without any cables and could be considered "one" camera body .. Venice is pretty small body.. way smaller than the Alexa or LF.. its more compact than an Amira come to think of it..
I didn't realize Class 480 went up to 960 for high speed.
I think it's an exciting looking camera. I know the body is smaller than an Alexa or LF. But it only does 10-bit without the recorder. With the recorder it's about the size of an Alexa or Amira. Maybe if they enable recording to an Odyssey for 444 or RAW that'll alleviate some of my concerns. That way I can mount the recorder to a gimbal if needed.
