The 72mm Fast Cap with Metal Ring from Op/Tech provides a safe and secure way to protect your valuable optics. The metal ring threads around your lens and holds firmly while the front lid of the Cap swings open on a firm hinge when you want to shoot. The lid contains a water and dust-proof O-ring that guards various contaminants from damaging your lens.
The system is easy to use. Just mount the base to your lens. It will stay put while you swing the hinge open to expose your lens. The Op/Tech Fast Cap offers you a way to never again lose your lens cap because it will always be attached to your lens.
