After almost a year of using this bag, I can do a little feedback: I need to carry a DSLR Sigma SD14 (not the smallest model of reflex, far from it!) With a 18-200, plus another zoom, 50mm lens, a flash, several batteries, charger , filters with me while having my wallet (containing my papers, credit card ...) more my cell phone and a few other things. Everything goes perfectly, so the capacity is quite large. In everyday life, it's a real pleasure to be able to leave the device in an instant, by rotating the bag to reveal the side opening. The main strap is wide enough not to make the transport and uncomfortable for the moment no problem with the closures that seem good. Do not spoil, a cover fully covering the bag is provided, and I could enjoy this summer when I was walking and the rain invited itself. I really recommend it to any person looking for a compromise between the shoulder bag and backpack and that has a lot of things to carry. I finished on the price: frankly accessible without sacrificing convenience or quality. The look is discreet (it looks like a backpack "ordinary"). Great product
