The Lens Cover for the Canon 400mm f/2.8 IS II Lens (Black) 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 ideal for nature and outdoor photographers since it will help camouflage your lens from wildlife. It is also an excellent accessory for sports shooters and photojournalists who are regularly subjected to less than optimal shooting and climate conditions.
It includes a clear plastic window located in such a position that you will still be able to maintain access to all lens functions including reading the distance scale. There is a handy alignment spot that will make mounting the lens to your DSLR body easy.
The LensCoat Lens Cover also provides a thermal barrier, protecting your hands from cold lenses in lower temperatures. It is easy to install and remove, leaving no residue on the lens. The LensCoat Lens Cover is waterproof, providing protection in harsh conditions. As a result of the increased protection this covering offers, it will in the long run, help preserve the resale value of your lens. This version comes in a matte all-black finish to better blend in where desirable. Or, it can be used just for its protection value.
