The Lens Oak from EasyCover fits onto a Nikon 200-500 f/5.6 VR lens, covering it with a 100% closed-cell neoprene coat and protecting it from bumps and scratches to preserve its value and condition. Its design provides a thermal barrier between your hands and the lens surface when working in colder temperatures, and it is also waterproof so your lens is protected when you are working in rainy weather. Suited for photojournalists and sports shooters, this cover breaks up the shape of the lens to make it beneficial for wildlife and nature photographers as well.
