I bought this cover for the M.ZUIKO 45mm. She does not look so chic like the original panel but fully meets its purpose. The bezel is screwed onto the lens, the lens cap can then still just starting and attach. Since the diaphragm is made of rubber, they can also "fold". The shutter makes a high impression.
Meanwhile there is also a panel of JJC is similar to the original panel. Thus the quite respectable 45mm lens comes naturally to better advantage.
