The realtree AP snow Telephoto Lens Cover for the Sony 500mm f/4 G Lens from LensCoat is a 100% closed-cell neoprene coat that protects the lens from bumps and scratches. It is ideal for nature, outdoor photographers, sports shooters and photojournalists. It also provides a thermal barrier, protecting your hands from cold lenses in lower temperatures. The cover is waterproof, providing protection in inclement weather.
The cover contains a clear plastic window through which you can access the auto focus and distance scale. There's also a handy orientation hole that aligns with the red dot on the lens for easy mounting even with the cover installed. This version comes in white and is covered with a subtle pattern of leaves and branches to help camouflage the lens when shooting outdoors.
