OP/TECH USA Lens Mount Cap for Nikon Lenses

The Op/Tech USA Lens Mount Cap is designed with an o-ring seal which creates a positive contact with the full perimeter of the lens mount area to lock out dust and moisture. It also offers a tighter friction fit over traditional caps that come with the lens so that it provides better protection to the lens mount area. This ensures that the lens mount cap is securely held in place while in storage or transit.
