The quality of interior partition panels is questionable, you can not really move them wherever you want and rigidity is woefully inadequate ... if you keep a few empty slots, the walls are deformed and crushed quickly, especially around the box + lens. The upper compartment is big enough pockets with 2/3 battery slots nets and / memory card, but I would have appreciated even more inside because fasteners while it ride a bit when we pass in front of the bag slingshot. To also be aware that the top compartment is not hermetically separated from the bottom, small objects fall therefore necessarily around the Velcro divider panel.
Otherwise, access to housing by the right, left, front, configurable at will straps (backpack or sling), the top handle, rain cover and tripod hook for large 50-70 cm are really practice and we do not really find this kind of functionality for the price in the competition. They also had the good taste to add two straps / hooks / hooks on the right and left side if you want to hang something else. Overall a great product but it works best when completely filled.
