The black Lens Cover for the Sigma Extender Set from LensCoat includes covers for both the Sigma 1.4 and 2x lens extenders (a.k.a. teleconverters). These covers are made with 100% closed-cell neoprene, offering protection from bumps, jars and nicks. They also allow you to blend in with your surroundings and help make you less noticeable to wildlife. They are useful for nature and outdoor photographers, as well as sports shooters and photojournalists.

Two small holes line up with the red dot indicators, making it easy to quickly line up your extender with the camera mount and lens with the cover installed. There is also a hole for the extender release. This version is matte black to better blend with your surroundings in low light conditions. Or, it can be used just for its protection value.
