The Thinktank Mirrorless Mover 5 is a tiny bag designed to hold a compact mirrorless camera: not one of those big ol' professional ones, but a smaller one, like an X-E3 or a A6000 with a very compact lens- or a point-and-shoot. Interior dimensions are approximately 7x9x13cm, so if you've got a lil' camera that will fit, this is a pretty nice carry bag.
