Lens cap has a hole for the captive cord if you do not like to use the sticky anchor.Overall I’m happy with the caps they are a good fit and were a good price.

Perfect replacement for lost lens cover and the elastic tag means now it won't get lost again

They are essential to help my elderly cameras lenses from getting scratches or dust or dirty fingers on them

Perfect for camera lens

The lens caps are the correct size and seem reasonably robust for the price paid. However, the "centre pinch" mechanism is difficult to operate because the finger grips are small, shallow and shiny and the springs are quite strong.Degreasing the grips by washing in soapy water and then carefully drying them improved operation a bit but to make the mechanism truly effective it was necessary to roughen the finger grips with some emery paper. After doing the modification the product performs quite well, providing the user has fairly small fingers.Subject to the above comments the lens caps work as expected and are probably worth the money paid.

It's a lens cap. It's accurately made, the spring feels like it will last, it doesn't cost very much and you get a spare in case you either lose it (which is probably the reason why you are buying this one) or if you get another lens with the exact same thread size. And then lose the lens cap.The only thing I have against it is the string. The sticky pad is tacky (pun intended) and I threw that away immediately. I then put the string through the hole in the cap and attached the other end (which is elasticated) to my neck strap. Unfortunately, because I have a long(ish) zoom on the camera, the string and elastic were at full stretch and it was awkward getting it to fit on. And then when you remove it again it's just left there, dangling in mid air or flapping about.So I ditched the string altogether and just hope that I don't put the cap down somewhere and forget it. And if I do... I've got a spare.
