We were looking for a camera bag for our Canon Ixus 220 HS and chose this. The camera fits in exactly, the pocket is thus not much bigger and not too small. Thus it does not unnecessarily take up valuable space in pocket, backpack or pocket. Inside it is well padded and the two outer shells make very robust, so that the camera is certainly well protected and should anything happen, if you take what is in your backpack on the camera bag or they might even fall off (we did not try it :-)). There is an additional compartment for another memory card. Whether a replacement battery even with fits in the bag, we can not test, but I think so. Den you should but then maybe leave in a film, so that the then not scratch the camera, because there are no more extra inside pocket. So that the product meets our expectations of a camera bag at a good price.
