Hi guys, Recently bought a new zoom lens (17-55mm f2.8 Canon) and the barrel physically extends at the end. Because it was second hand and therefore has been used before and the joys of gravity it is exhibiting the signs of zoom creep. I have read online that putting some tape on the barrel will just add a sufficient amount of thickness so that it doesn't creep on it's own. Has anyone tried this with their lenses and does anyone have any other tips or suggestions? Thanks!
