Unrestricted 5 star: the original closure of JJC - ALC-5B (ie not a cheap no-name copy) is awesome for the Lumix DMC-LX5, functioning properly and interferes with photographing or filming in any way. The handling is easy: - Front lens ring (Front Threat cover) Unscrew - Lens Cap Screw, - Done! Could not be better, unless Panasonic brings one day the successor to the Lumix DMC-LX5 with a built-in lens cap on the market, which appear at the LX5, as opposed to older models of the series DMC, simply "forget" was.
