The Lens Cover for the Canon 300mm f/2.8 IS II Lens (Realtree Max5) from LensCoat covers the lens with a 100% closed-cell neoprene coat, offering protection from weather, bumps, jars and nicks. Available in several different designs, this protective coat will allow your lens to blend in with your surroundings, making it useful for nature and outdoor photographers since it helps camouflage your lens from wildlife. It is also an effective accessory for sports shooters and photojournalists who are regularly subjected to less than optimal shooting and climate conditions.
