I bought it for my standard lens 14-42 on the Olympus PEN PM1, since the original was lost. This lens cap is despite the low price of good manufacturing quality. He sits properly. The ability to secure him on a string against loss, is a nice feature for people who do not mind the Gebambel when taking pictures. Given the price I refrain and instead have equal bought a further cap as a replacement. So I can fully recommend the part.
