For FZ100 this bag is recommended. The camera fits in exactly, which means it can no longer slip and sits very safe. It brings an extra battery and an SD card with still, but then almost the end is in the field. It should be mentioned that the battery is in the camera, separated by a sewn microfiber cloth, so whenever you take out the camera has to be considered. In slimmer cameras is not a problem, however, is at a bridge of this size it is no longer different. Processing well and allowed to drop the bag again, this is no problem for the content. ;)
