Summary: A great, light backpack if you don't want to take a lot of gear with you. It comfortably holds my DSLR including the lens, two other (small) lenses and a flash. It won't fit any tele zooms though as the camera is in the backpack sideways.
Pros: Comfortable, Easily Accessible Equipment, Strong Construction
Summary: Good for basic transport of SLR and one telephoto lens. I have a Canon XSi. With the 18-55mm lens attached and the 55-250mm in the adjacent padded section, the bag is perfect. If you have lots of lenses and auxiliary equipment to lug, this is not the bag for you. Even an external flash would just fit in the upper storage section. The pockets and mesh are helpful for SD cards and extra batteries.
