Tamron Front lens cap MkII 77mm

I needed a 77mm cap that actually stays on in my bag, and this one clicks into place firmly without being too tight. The pinch mechanism works smoothly one-handed, and the fit is precise enough to keep dust out. Exactly what I was hoping for.

The spring-loaded center pinch mechanism is really smooth and easy to operate one-handed. It clicks on with a satisfyingly solid feel and seems to seal well against dust. I’m glad I went with this design over the traditional pinch style.

The spring-loaded centre pinch makes it way easier to pop on and off than my old style caps, and it feels solid against dust. Snaps into place with a satisfying click every time.
