キヤノン レンズダストキャップ E（リアレンズキャップ）

I’ve bought cheap rear caps before that wobbled, but this one clicks on solid and stays put even when I toss it in my camera bag for travel. It’s exactly what the EF lens lineup needs, and the fit is reassuringly tight every time.

Snaps onto my EF lenses with a reassuring click—no wobble at all. The tight fit gives me peace of mind when I toss a lens in my bag for travel.

Finally found a rear cap that actually clicks into place securely on my EF lenses without any wobble. It's lightweight and perfect for throwing in my travel bag between shots.
