Tamron 72mm スナップオンレンズキャップ II

Finally, a snap-on cap that doesn't fight me every time I need to take it off—the spring-loaded center pinch mechanism is smooth and reliable. It clicks securely onto my 72mm lens, and the build feels solid enough to keep dust and moisture out.

The spring-loaded mechanism on this 72mm cap snaps on securely with just a light pinch, and it hasn't popped off accidentally once. I appreciate that it covers the entire front element without any loose fit.

Finally, a snap-on cap that actually stays put—the spring-loaded pinch mechanism is much more secure than the push-on kind I've used before. It's a perfect fit for my 72mm lens and keeps dust off the glass.
