After a long search I found this model and am very happy with it. It is just right for the FZ18 from Panasonic. It is lightweight and has a front still trade by can accommodate a spare battery and a memory card. The belt loop is good. It is attached by a velcro belt and additionally secured by a push button. I find that very convenient, because you do not always have to pull the belt out of his trousers. All in all, a very good alternative to the original bag.
