After mulling around a few of the reviews out there, we picked up the Sennheiser to use as a boom mic. We've been very pleased with it. We use it on a pole rather than on any of our cameras. On a whim I tried attaching it to the EX-1, but its diameter is too small. I haven't had the need or opportunity to find some foam or something to make a liner for it. Our EX-3 is on order, I'm interested in seeing whether it has the same inner diameter on the mount.
