The LensCoat Telephoto Lens Cover for the Sigma 50-150mm f/2.8 OS Lens (Black) 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. 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.
