The Lens Band Stop Zoom Creep for Zoom Lenses (dark blue) is a unique solution to an age old problem. When using zoom lenses, especially extra long zooms, there is often a tendency for the lens barrel to "creep", i.e. extend due to its own weight when pointed either upward or downward. The Lens Band presents a simple and unique solution to this issue. The strong silicone rubber band stretches over the zoom ring of your lens and holds it firmly in place.In addition to preventing this kind of problem, it also aids when shooting with a tripod where slower shutter speeds may be required, such as in macro photography when operation of the zoom ring may not be required. For anyone who works out in the field and carries or hangs his camera over his shoulder, lens creep is a common problem that can cause undo stress on the both the lens and your back. The inexpensive Lens Band offers you a straightforward solution to this potentially nagging problem.It's easy to use. Stretch the Lens Band over your lens. Position it over the zoom ring when not in use. When ready to use it, slide half of it over the non-moving portion of the lens body. The pressure of the band will prevent the lens from slipping out of place. Just make sure the Band does not interfere with your focus ring. As an added benefit to the Lens Band, it can also be used to remove filters that have become stuck. It works on filters from 67mm to 110mm or 2.75" (7.0 cm) to 4.5" (11.4 cm) in diameter. Wit
