they do! https://www.blackmagicdesign.com/products/blackmagicmicrostudiocamera4kBM Micro indeed. 13 stops. Native ProRes 422. This would be the bird to lift it. Though we still need a gimbal suited to the micro. And I really wish BM did a 4K or even a 2.8K version with built-in recording.
a) The handheld gimbal is described as "modular" and DJI employees have stated it is the intent to make camera upgrades that will fit the Inspire.Where did we hear about the x5? from the matice product launch?
What's amusing is that the makers of all 3 of the cameras you mentioned were not players in the imaging market very long ago. Many people said the same about Panasonic when they decided to get in to cameras......DJI will never make a camera as good as those in the business of making cameras. I would have an Inspire right now if I could hang a fully stabilized non-DJI camera under it. Sony RX100, Black Magic, and even GoPro H4B.
