This is a 4K ENG style Camera with only PL lens mounts (unlike BlackMagic having Canon EF Lens models) and even without a viewfinder (except a small LED on the left side). I will cost $8955, and doesn’t even have a viewfinder, but can use industry standard ones, and rails and batteries. You will need to get AJA storage though, as it uses yet unpriced AJA Pak SSD drives and a USB 3 Dock for them, unlike the BlackMagic which uses CFast 2.0 Media.
It does seem to be more a standard size and use more industry standard accessories than BlackMagic, and has a higher resolution recording capabilities, even without a replaceable sensor.
We will have to wait and see image quality, but this 4K APS-C sensor camera is certainly going to give BlackMagic a run for it’s money.
