The Lens Cover for the Canon 400mm f/2.8 IS II Lens (Realtree AP Snow) from LensCoat covers the lens with a 100% closed-cell neoprene coat, offering protection from weather, bumps, jars and nicks. Available in different finishes, this protective coat will allow your lens to blend in with your surroundings making it useful for nature and outdoor photographers. It is also beneficial for sports shooters and photojournalists since it provides a thermal barrier from cold lens surfaces when shooting in lower temperatures.
It includes a clear plastic window located in such a position that you will still be able to see and access lens functions including the distance scale. There is a handy alignment spot that will make mounting the lens to your DSLR body easy.
The LensCoat Lens Cover is easy to install and remove, leaving no residue on the lens. This cover is also waterproof, providing protection in wet conditions. The increased protection this covering offers can help preserve the resale value of your lens. This version is white and covered with a subtle pattern of leaves and branches to help camouflage the lens when you are shooting in snowy conditions.
