Very practical bag contains an SLR without problems with 2 zooms (EOS 500D + 18-55 + 55-250 for me) and all the necessary accessories battery, charger, memory card and various cables to connect to the TV or the computer . by cons if you have a 3rd zoom, it can hold as in (2 side pockets can contain more zoom on a camera) but I think it will make a choice on accessories or so all the stuff main pocket (it can go). I am not a specialist in large telephoto lenses but you still have to check the size before because the pockets are not huge. The whole looks solid, one will see a use if that is the case
