The Realtree Max5 Lens Cover for the Sigma 70-200 2.8 DG OS AF Lens from LensCoat wraps the lens in a 100% closed-cell neoprene jacket to protect the lens from bumps and scratches. It is useful for nature and outdoor photographers as well as sports shooters and photojournalists. The cover helps break up the shape of the lens, making it less noticeable to wildlife. It also provides a thermal barrier, protecting your hands from cold lens surfaces in low temperatures. The cover is waterproof, providing protection to your lens in wet conditions. The cover is easy to install and remove and will leave no residue on your lens.
There is a clear UV-PVC window over the lens controls and distance scale that make it easy to activate the AF/IS/VR controls. For mounting purposes, there is a hole that helps align the lens with the body.
