Nikon LC-72 72mm Lens Cap

I was worried it might be too loose, but the spring retainer ring holds it securely even when I toss the lens in my bag. Snaps on and off with a satisfying click, no wobbling.

Finally, a cap that actually stays put on my 72mm lens—the spring ring holds tight without scratching the glass. I've knocked it around in my bag a few times and it hasn't popped off once.

Lost my old one on a hike and this replacement fits my 72mm lens perfectly, the spring retainer ring snaps into place with a satisfying click. It’s light but feels solid, and I like that it doesn’t wobble once it’s on.
