This rocking distance is less than a hair's width, right? Mine has always done that, from new. If you push on the front, eg against the lens hood, it clunks ever so slightly and you can see and feel lateral movement, but it's a sub-millimeter distance. I assume it's because plastic can't be machined to the same tolerances as aluminum (eg Ltd lenses).
