Hey guys!

So I got this lens from where I work, and it would be a great workhorse for corporate work really, just seeing if I can get it working.

It's a Canon BCTV Zoom lens, B4 mount. T1.4 7mm-119. YH17x7

I'm sure adapting it to MFT won't be the issue, but the image circle may be? I see there is another ring, that may be for back focus, it has a labe for F.B and 1/2"

If there would be vignetting with my MFT, is there some sort of optical doubler or whatever that I could add. It's a super fast manual zoom, so I'd LOVE to get it to work. Here's some pics.

I'm afraid you're going too be out of luck with this lens.
It's designed for a 1/2inch chip so even a doubler (which would soak up 2 stops of light, so no longer a fast lens) wont cover the BMCC chip.

That lens is 1/2" Sony mount.

If you had an actual B4 mount lens, you could convert it with this: http://www.abelcine.com/store/HDx2-B4-P ... l-Adapter/
