I can only answer you from my own experience...
Originally I ordered EF mount, but as soon as I heard of MFT I changed my order.
My reasoning is this:
1. I have wonderful vintage Carl Zeiss 85mm f1.4 (not easy to get but possible to find in ebay for around $800) and LOMO 35mm and 24mm Russian film lenses (extremely inexpensive). These look so great and better than any lens I have seen (way better than Canon lenses), and need very cheap lens adapters that you can find on ebay.
2. As BMC is smaller sensor camera than EF-S and MFT cameras, you need fast wide lenses for shallower DOF, which are difficult to find for EF mount. I m planning to get SLR Magic 12mm f1.6 (again not expensive), and Voigtlander 17.5mm f0.95 & 24mm f0.95. These last two lenses are not on the cheap side, but are incredibly fast and high quality lenses for their price, and again way better than anything I can find with Canon.
This set will cover all ranges for my needs (with possible addition of Samyang 8mm - which works on both EF and MFT). Now all my lenses are prime, as I hate shooting with zoom lenses (I don't really need zoom as I only shoot dramatic scripted stuff) - so it really depends what type of productions are you planning to film.
Check out some articles about all this on eoshd.com and philipbloom.net
Both of these guys are blessing for us low budget independent filmmakers.
Hope this helps...
P.S. I m more worried about when my BMCC is coming, as it looks like I will loose two jobs - a short and a feature because I expected to have camera in my hands by the end of the year. God knows if we'll ever have it. If I had more money I would either go for a RED or even risk it with Chinese Kineraw s35.
