It's funny: when I picked up the lens yesterday, I looked at the connection, tightened up the clamping bolt and thought "what's the fuss about? Perhaps Nikon have changed the design since people's initial experiences", as it seemed secure. Of course, I haven't taken it out into the field, yet, but it survived the couch test
. Having said that, it's happened to enough people to make one think "why take the risk?".
What I'm also thinking is, to use the lens with my tripod, I have to attach my Manfrotto plate to the foot, and the plate is much longer than the foot, meaning that I can grasp it further away from the release mechanism, which might help.
