Precision Snap-On Lens Cap For Lens

The Center Pinch Snap-On Lens Cap from Precision is a front lens cap with a squeeze, spring and snap-on mechanism.
They're easy to put on and take off, especially when using lens hoods, and they stay on.
Lens caps protect your lens from scratches, fingerprints and the elements when the lens is not in use.
It's always good to have a spare in your camera bag, too.
