The made in the USA, black Lens Cover Set for Sony FE 1.4x and 2.x Teleconverters from LensCoat is constructed from 100% closed-cell neoprene for protection from weather, bumps, and scratches. This cover helps your extenders blend in with surroundings, making it useful for nature photographers, sports shooters, and photojournalists. This version is matte black to better blend in where necessary. Or, it can be used just for its protection value. Two small holes line up with the white dot indicator, allowing you to quickly line up your extender with camera mount and lens with the cover installed. It also has a hole for the extender release.
The LensCoat provides a thermal barrier, protecting your hands from cold lens surfaces and teleconverters in lower temperatures. It's easy to install and remove, leaving no residue on the teleconverter. The LensCoat is waterproof, providing protection to your lens in wet conditions, and it can help preserve the resale value of your gear.
