Really, really good news out of Blackmagic today, as they just informed me that they have updated the firmware of the Blackmagic Production Camera 4K to allow for in-camera formatting of the SSD. So will this be coming to the Pocket Cinema Camera and the Cinema Camera? Yes, yes it will.
You can download the new Firmware v1.9.5 so you can now directly format an SSD to HFS+ or exFAT within the camera. This is a huge deal, as one of the few remaining gripes about the system is now solved.
I was also told that they will be rolling out this functionality in the Blackmagic Cinema Camera and the Pocket Cinema Camera shortly, and if the wait time is anything like the last firmware update was, that means we should see it in one to two months if not sooner.
