TheTimbuk2 Espionage Camera Backpackhas 5 basic compartments: a hard-sided camera compartment at the bottom, a large zipper compartment built into the camera compartment opening flap, a medium size rucksack-like area above of the camera section, a full size laptop sleeve, and a phone compartment. It also has external straps to hold a small tripod along one side and a water bottle along the other side.
The large padded camera section — which can be customized with anti-scratch, tricot walls — can hold a decent amount of camera gear. A DSLR camera body with either a standard or telephoto lens attached, flashes, additional lenses, plugs, brackets, cables — pretty much most of what you would need on a regular day of shooting. The hard sides protect the camera equipment pretty well.
