A great little useful part! Losing the lens cap has put an end, at least if the lenses are no longer than about 12.5 cm. For my Sigma 18-200 that is not a problem. Otherwise I like it quite well, that only a small glue point is necessary and thus better suited to my lens cap. If the bands should break times, you can replace this certainly since the glue dot a small eyelet is present. Conclusion: I am happy that I have a small part!
