I've bought the protective filter DMW-LMC52E for my Lumix FZ 150 and have not been disappointed! It is very easy to screw onto the thread of the zoom lens, is firmly seated without getting in the thread "einzufressen", thus you get it even slightly down again, should eg pending a filter change. Have tested it in my 3-week adventure holiday and neither noticed any defects during handling even on the quality of my images. Although it may seem a bit high-priced as pure protection filter is well worth its money and to recommend the purchase!
