Based in Montreal Canada, I have my own company which one of its services are video and short-docs film production.
Please, could you share the info about it? I really need to do so cause BM seems to have forgot BMCC and BMPC users like me in order to get some slow mo features.
For daily use the c100 is a good way to go, but for a real films the BMCC is a better way to go. I own the BMPC 4k and the Prores image quality is excellent even at LT flavour which give you 5:40 hours of recordings for a 240 Gb SSD at full HD that you can easily upgrade to 2k in post because of the space for color grading Prores give you in post. Yes you have to keep in mind how to power up the camera and rig it, but if you can control in some way your environment on set you won't be disappointed.
En event is doable. Just for comparison here is a shooting for an event I made using the BM Production camera using Prores Lt full HD and a GH4 at full HD 100Mbit/sec. In post I tried to match the two but the difference is noticeable in terms of image quality when you want a film look.
