The Fast Cap is not only loss-proof, but it's dust-proof as well thanks to the integral semi-"O" ring seal. The Fast Cap is available in a universal design to fit most normal/telephoto and wide angle lenses.
Photographers agree that the Fast Cap™ is truly a winner. It is not only loss-proof, but it's dust-proof as well thanks to the integral semi-"O" ring seal. Once attached to a lens or filter, the base stays in place when the hinged, spring-loaded lid is flipped open by a flick of the thumb. The wrap-around design of the Fast Cap™ lid effectively protects the rim of your lens or filter as well as the valuable optics. The cover can be adjusted for the most convenient position of the opening tab. The Fast Cap™ works well with older lenses. For newer lenses with fewer threads try out our newly redesigned Fast Cap™ with Metal Ring.
Your OP/TECH USA Fast Cap™ lens cover consists of three parts: plastic cap, camera ring and threaded adaptor ring.
How to Attach Fast Cap to your Camera
1. Take the entire assembly as packaged and screw it clockwise into your camera or filter as though it were another filter. (To first start, turn counter clockwise a quarter turn.)
To close: Press firmly in the center of the cap to insure a tight seal.
To remove: Close cap and unscrew as you would a filter.
For best results, annually lubricate the inside lid ring with a cotton swab and a light touch of silicone.
Protects my lens, never loose it, no "strings attached! I can't believe it isn't standard with all cameras. I just wish it was available for my 72mm lens also (I use it on my 58mm Lens).
