The black Lens Covers for the Nikon Teleconverter Set from LensCoat includes covers for the Nikon 1.4, 1.7 and 2x TC-20E III extenders. They cover each extender with a 100% closed-cell neoprene coat, offering protection from bumps, jars and nicks. These coats allow the lenses to blend in with your surroundings and 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 indictor, making it easy to quickly line up your extender with 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 in where desirable. Or, it can be used just for its protection value.
