QuoteWhat lens mount is it?
It's micro four-thirds. I have the original pocket and used Nikon lenses with a Metabones speedbooster adapter and it worked really well,  there are adapters for Canon as well. I think I'll have to get a new type of adapter for this new model,  but still cheaper than replacing a bunch of lenses. 
QuoteOh, and why do camera manufacturers insist on providing filters/LUTs to be baked into recordings?
You don't have to bake a lut in,  in fact Blackmagic's whole ethos is to provide flat footage that is super gradeable in post , but it is there as an option,  I guess it's there for journalists - who might have to get something to air quickly without having to go through post,  the inclusion of professional 3D lut's is a really good idea.
