This bag really fits like a glove, when you first put the battery at the bottom of the front, small pocket. Then you can do the RX100 as in the normal case that the lens rests more or less "on" the battery, so you have a bag that is really compact and the camera offers good protection.
Also inside this bag makes a classy look: the material is not floating, but very soft, a kind of microfiber could be. This is ideal for high-end cameras, so you risk no scratches on the screen.
