Not a cine lens, and Rokinon/Samyang has a history of making shitty lenses.
It's just "raw," not "RAW." It's not an acronym.
You have a point about the bulk, but you can adjust the recording format if you don't like the file sizes. BlackMagic gives you ProRes, which is 700 Mbps vs. the relatively lame 400 Mbps you're getting with Panasonic's update.
Not to mention that you also get built-in raw, if you want to do some green-screen work.
BlackMagic's biggest problem is crap-ass low-light performance. That should be their top priority right now, but it has gone unaddressed year after year.
The C200 is interesting, but that viewfinder placement is embarrassingly inept.
This tells us jack shit.
8K with a Four-Thirds mount? That would be asinine.
It "supports" them? How? What does that even mean?
