Designed to protect the Canon lenses, the Lens Coat for Canon 100-500 f 4-7.1 L IS Realtree Advantage Max 5 safeguards against abrasions & impact when working in the forest. The lens coat features a camouflage pattern to blend easily with the natural surroundings of forest, lake, river, etc., making it less noticeable to the nearby wildlife, if any. Engineered with a thermal barrier, the lens cover keeps the hands warm while working in cold conditions, facilitating comfortable & productive photography. For easy workflow & functionality, the foldable lens coat is equipped with a plastic window allowing full access to image stabilisation & autofocus controls. With a convenient zoom sleeve, you can cover the lens that becomes exposed while zooming. Also, an additional tripod collar section is added to hide the lens while working with tripods.
