Tamron 72mm Snap-On Lens Cap

Finally, a lens cap that stays put even when I'm hiking through brush, and it still clicks on and off easily with the hood attached. No more fishing around in my bag for a popped-off cap.

Finally a snap-on cap that actually stays put even when I’m hiking with my camera swinging from the strap. The way it works with a lens hood attached is a lifesaver for quick shots.

Snapped this right onto my 72mm filter thread while the hood was still attached — no more fumbling around. It clicks on firmly but pops off easily when I need it, and I haven’t had a single accidental fall-off during hikes. For the price, it’s a simple upgrade that just works.
