So again, cinema cameras aren't FF 35mm for practical reasons. One such reason is that 35mm is a different aspect (so the camera is having to do interpolation anyway). They're also sticking with set standards, like super35 format, so that crews can use their previous equipment.
Look, Canon's 1DXII and 5DIV cameras, as well as Sony's A9 camera, shoot 1080p video in full mode.
The A9 shoots 4K in full mode as well - while the 1DXII and 5DIV shoot 4K only in crop mode.
So, if there is a practical advantage to shooting in crop mode, then this advantage applies only to Canon cameras and only for 4K.
I wonder what that special advantage is?? LOL
The reason (some) cinematographers use DSLRs is for the 'unique photographic look'.
Yes, it's a cliche - and yes, the cliche is true, as that's what they are after.
That's the advantage of a FF sensor when it comes to video.
Note that the 'unique photographic look' look is lost when you crop.
Well, if you need more 'reach', then it certainly makes sense to shoot in crop mode.
But that's not the reason why the 1DXII and the 5DIV can only shoot 4K in crop mode.
