At the recent UK photography show I had a chat with the people from Venus Optics about their Laowa lenses - and followed up with their chief lens designer.
I've tested all EF mount Laowa lenses over the last few years and have written up a short interview with some of their comments at:

Perhaps not as detailed an interview as I might have liked, but translation does make it a bit tricky
It seems that they are going to be showing some new cine lenses too, in the near future
