I got this case for my wife's camera (A Panasonic Lumix DMC-TZ8) as her previous case was a bit too bulky to put in her bag along with her purse, keys, umbrella, kitchen sink etc.
It is almost as if this case is made for that particular camera, it fits perfectly. There's no spare room inside the case but that's fine for our needs. There is a small zip pocket on one side of the case that is big enough for a couple of spare batteries (depending on the size of them I suppose, but based on the size of the camera that will fit in the case, the batteries can't be that big!) You could also get a few memory cards in the pocket or a combination of cards and batteries.
The zips feel like they are good quality, as does the rest of the case. There is also a belt loop on the back and a basic caribena clip (it has no mechanism to lock it closed).
If you're after a small and cheap camera case then this is probably what you're looking for.
