Tamron 86mm Front Lens Cap

The center pinch design works perfectly even with my hood attached, saving me from the usual fumbling. It snaps on with a reassuring click and stays put, which is a huge relief after losing cheaper caps.

The pinch-and-release mechanism works perfectly even with my hood attached, which is exactly why I grabbed this one. Snaps on with a satisfying click and stays put in my bag, no more digging around for a lost cap.

Finally, a lens cap that doesn't pop off in my bag every time I grab the camera. These clip on and off easily even with the hood attached, which has saved me so much fumbling. They're snug enough that I've stopped double-checking they're still on.
