100-400 lens

Has anyone had a problem with the screws coming loose on their 100-400 lens?? If so what did you do to fix it?? Thank you.

My version one of the 100-400mm zoom never missed a lick.  Even though it always got bad press as a dust pumper. No issues at all.

EOS 1DX and 1D Mk IV and several lenses!

A tiny dab of blue loc-tite applied from a toothpick works great.  "Less is more"
