The L2 bag is shown here with Canon 20D and 17-85 IS lens attached.
On the left side is a 70-300 DO IS with hood reversed. Separaters came with the bag, and one is positioned here between the camera with lens pointed down and the zoom on the left.
There is room on the right next to the attached lens, for small items, or to fold up the strap.
Also there is a full width open pocket between the bag exterior shell and interior liner.
