Zoom creep can occur when the zoom gear of the lens is loose. The lens slowly starts zooming in if you keep it facing downwards, or zooms out if you keep it standing upright. It is most common in superzoom lenses. In some cases,the lens may not show zoom creep when it is brand new, but repeated use and wear and tear will bring about this problem.
Zoom creep can be particularly problematic while shooting long exposures. After all, the lens may slowly zoom out, if you have kept it facing the sky to shoot a star trail! To combat the problem, some lenses have a zoom lock function to minimise creep. Alternatively, you can tie a tight rubber band around your lens to ensure that it does not slip up and down.
