The often very unpleasant and penetrating odor of neoprene is very discreet and was hardly noticeable for me. The FZ1000 fits into only with reversed hood and one has to use both hands to get the camera in the rather narrow opening. This would calm can be a bit bigger. This also applies to the case, it acts on all sides of a few millimeters to small.
I use the bag for transport (eg aircraft) or for storage when not in use. For use during a photo tour (rausholen, make photo, pack ....) it is not suitable, because too cumbersome in my opinion. Since I use my shoulder more.
