I bought this bag because I had to buy a gun 100/400 and I had to take two bags mare to take pictures. I must say that if a bag is exactly what I wanted. I can put my eos 350d with my 100/400 18/55 and 70/300 + I, and there is still space. Moreover I will still add a camera, a ordit 17 "and many other things. This bag is very ergonomic with storage is everywhere, brief happiness. First order from Amazon and I am not disappointed! Delivery expected delay and prepare parcels thank you.
