The Lowepro Photo Hatchback 16L AW Backpack is an excellent design to hold your DSLR with an 18-55mm Lens attached and two additional moderately sized lenses, flash, accessories as well as your iPad or tablet held safely within its own Dedicated compartment. The bag comes with a removable camera box which, when removed, turns the pack into a full-fledged, empty pack that can be used as a daypack. The camera box comes with a storm flap for protection and two handles for easy removal. Load it beforehand, place it in the pack and you're off. And, on days when you don't need it, just lift it out and the pack is ready for clothes, books, food, jacket or groceries. Access is via a top loading zippered opening or its very handy side "hatch" for rapid retrieval of your camera when the shot appears. All the zippers are YKK for added durability. The 2.0 lb pack is comfortable with its adjustable backpack straps.
