This photo Trolley is practical, looks visually good and expected for most airlines go through in terms of its extent as hand luggage (for me it has worked at least without objection). The inner foam pad can be fixed variably with Velcro. A DSLR (but without scheduled battery grip) with attached zoom lens is sufficient and well padded as well as other lenses and extensive accessories space. Also space for a laptop is provided. Stands can be mounted externally. Taking the "inner life" out, it becomes a normal travel trolley. Optionally, it can be transformed in a few seconds the backpack. He could be perfect, but its "stability" not up to scratch. Since the heavy camera up (it is supposed to be readily accessible) is seated, he quickly gets the status overweight and tilts forward to. The single large round embossment base, which is attached at the bottom center of the front edge to prevent it in opposition to the rear seated roles well, but it does not. So you have it with the front leaning against something, lie on your back or on the extended trolley handle hold to prevent it from tipping. Annoys me that a little, so a point deduction.
