Just Ltd have launched Lens Band. This band stops lens creep, which can occur when a camera with a large lens is tilted up or down and the lens zooms in or out without the photographer's knowledge.
Lens Band is a patent pending silicone band designed with just the right amount of elasticity to stop lens creep.
Peter Brogden from just Ltd said: "Some manufacturers fit zoom locks to their products, but many don't. Of course, some lenses are fine when new but develop a bit of creep as they age and the zoom mechanism wears a little. You can't turn off gravity, but neither can you always hold your lens horizontal, so frustration sets in when lens creep occurs during normal use – and there’s always the risk of serious damage too."
