Q: 2. I own the FE 100-400mm and the original foot now shows a looseness even when screwed in to the max. The Looseness is from front to back. Unless I am mistaken, orginally there was no looseness. I am wondering if the design of this replacement will address this issue and offer a perfect thightness? Thanks!

A: I can answer my own question... The problem was not with the removable foot as I thought, but with the fixed portion on the lens where the removable foot attaches. That silver metal piece is screwed in the body of the lens. The screws unscrewed themselves due to vibrations in the Jeep on an African safari. I have now used removable Blue Loctite to insure that it does not happen again. I wanted to share it so that others can do prevention in making sure it does not happen to them and inflict bigger damage.
