Bought this for a trip out west this summer. I wanted to be sure I had easy access to the lens that I needed, but wanted something more comfortable than standard camera bag. This fit the bill. The only drawback are 1-lack of space for water, 2-the dividers didn't stay in place with heavier lens, 3-not really lockable. I really liked 1-the waterproof cover for unexpected rain, 2-very comfortable straps, 3-capacity good for day trips
