Tamron 72mm Snap-On Lens Cap

Finally, a snap-on cap that doesn't launch itself into a puddle every time I pull out my camera. The fact it stays snug even with the hood attached is a huge time-saver.

This cap fits perfectly over my lens hood, so I no longer have to fumble with a center-pinch design. It snaps on securely and hasn’t popped off in my bag once.

Fiddling with caps while a hood's attached used to drive me nuts, but this one snaps on and off cleanly without me having to remove anything. It's also reassuringly tight—I've tossed it in my bag a few times and it hasn't popped off once.
