The IXUS 100 is a really megakomptakte digital camera, but with this bag this advantage is made to a large extent canceled out. The camera bag is just too big cut (even air betw. Camera and inner shell) and the leather is not exactly thin. I put the IXUS like in your pocket, though everyone in my pockets with this bag, but compact looks different. Who the size does not matter, you can recommend this bag anyway, since it is quite fast to open and close, looks very classy and is really well finished.
