this is just the bag if you want to pack all your camera equipment as you walk or hike from point to point. great space,,it holds all my lens,batteries,excessiories,and i can strap my tri-pod to the outside as well. the only feature that is somewhat lacking is the waist strap being unpadded and it could use a little more adjustments. i just used it on a 3 day trip at the grand canyon and used it everyday. would buy it all over again.
