The black Lens Cover for the Sigma 300mm f/2.8 APO DG Lens from LensCoat covers the lens with a 100% closed-cell neoprene coat that protects the lens from bumps and scratches. Ideal for nature and outdoor photographers, and for 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. This version comes in white and is covered with a subtle pattern of leaves and branches to help camouflage the lens when shooting outdoors.
