The lens cap is not only one of the best, but one of the best I know. The reason is that it is modeled on the Hasselblad lens caps. The mechanism for the lid agree is on the inside, not outside, which you only really with the two thumbs abbekommt the lid. As a result, the lid does not dissolve well in case of accidental contact with other objects and thus is hardly lost (is me gone so far never lost). Therefore, and because the price is in my opinion the best lens cap I've seen so far!
