But space is just below ground for the external dimensions. I would even go so far as to say that was cheated by the manufacturer in the product images. I happen to own that, among other things shown there EF 70-200 f / 4 and in my copy, it can not be definitely not tuck as shown, at least, albeit still to fit in the camera with attached 17-70. Also one of the main arguments for purchasing - at least for me - namely the quick access to the camera's mini. I have a 70D and this I just get with considerable force there squeezed. With shoulder belt (in my case the Black Rapid Sport) can forget it right away. Compared to the Case Logic Lowepro Flipside 300 is a pure space saver (especially in the far smaller external dimensions). Wanted to replace this really because me the aforementioned shortcut and the lateral attachment of the tripod had impressed. After this disappointment, it must just make a few more years of Lowepro ;-)
