If you have the budget, I'd say go for the
I2 because it's always nice to have the newest kit. But the x5 or x5Raw will give you
nearly the same quality as the
I2 but save you a fortune. I'd spend that extra money on lenses, memory and batteries. And a holiday. And a motorbike.
I personally cannot see how the
I2 with the camera is worth over double the Inspire Pro with the x5, but then I don't do cinematography. If your clients need that, then you need it too. But if not, don't bother.
