That surprises me. Was the boom pointed at the camera or some other subject? I will say that no, I don't think that the IS on the 70-200mm 2.8L can be heard by a boom in anything other than an absolutely noiseless room (and similarly noiseless pre-amp). Do you have a link to the video? I suspect the same is true about the 24-105mm 4.0L.
Problem is, while the 24-105 is wide enough, it probably isn't fast enough for what we might want for the BMCC. The 70-200mm is almost certainly too long for what you are concerned about (since the subject would be so far from the camera).
Again, it surprises me that you are that sensitive to that low a noise. Is IS absolutely necessary? For the quietest shots, can you simply turn it off?
