OP/TECH USA Lens Mount Cap – Nikon F

The OP/TECH USA Lens Mount Cap is designed with an O-ring seal which creates a positive contact with the full perimeter of a Nikon lens mount area, locking out dust and moisture. It also offers a tighter friction fit over traditional caps that come with the lens, providing better protection to the lens mount area. This ensures that the lens mount cap is securely held in place while in storage or transit.
