Zoom Creep is a lens’ tendency to slowly (or rapidly) extend or shorten, depending on the downward or upward tilt of the camera. It absolutely necessitates the use of two hands while using the lens and is problematic.
Several people have suggested different methods in dealing with this problem, my favorite being the use of a piece (or pieces) of “gaffer’s tap” along the barrel of the lens, to “lock it” at the zoom length you have chosen for your shot. Gaffer’s tape rarely leaves residue, unlike masking tape and such. Get a roll.
