One interesting note - Kirk sells a support bracket in addition to the replacement collar for this lens (a bracket that supports the filter side of the lens) which kind of tells me that their bracket might not be too much better in regards to collar flex. After all, if their replacement collar didn't flex, why would they offer a bracket to reduce that flex?

The problem with the collar is that the area for the collar on the lens is to thin, and placed very unbalanced, so even if the foot is complete sturdy, the lens is not sturdy. A second point in front of the lens address this.

I have the collar and foot from RRS, and even if it is better than the original, it is not rock solid. A cork pressed in between the front of the foot and the lens (between the zoom ring and the focus ring) makes it as good as it can get, but this does only work when the foot is underneath the lens, so it will not work on a sidemount gimbal.
