The bag has a removable insert which is padded, as if the bag for the frenzied photojournalist would made and the equipment would only thrown around in the area. I have separated the outer lining of the use and removed the foam rubber padding. It remains for the normal users still enough protection of the equipment. So I have gained approximately 20mm in depth and now the 100-400mm fits my Canon 5DII with attached 24-105mm lens and another extra lens, for example, each with attached lens hood loosely into it and there is still some space, for example for a midsize Metz flash. One point deduction there for several days lasting penetrating scent of the bag, pity. Otherwise, the case for the price of around 20 Euros is unbeatable.
