I have to admit that this lens hood of JJC really is the worst I ever had. She looks very cheap, does not clean off, does not lock properly and to not even really cheap. Provides for the M.Zuiko 45mm f / 1.8 any particularly difficult demands on the design of a sun visor? I wish I could buy neither these nor the original panel, because the price-performance ratio is bad for both, but there are few alternatives. I'll probably try it again with the rubber. If to not tell me, I will walk around without protest.
EDIT: I've now bought the B + W rubber lens hood and am fully satisfied. The is well made and I can always leave it. In my opinion, the best alternative for the M.Zuiko 45mm. Certainly rubber Geli's always a matter of taste, but I can only recommend a try.
