About as close to perfect as you can get for a camera backpack. There are just three things I would change:1. Add a pocket that can hold several lens filters.2. Move the opening on the slips on the sides of the bag to the top and bottom so I could attach some external cases. Maybe something like the MAS system on the Tamrac bags. I can't for the life of me find anything useful to attach to the outside of the kata.3. Make it so that cameras like my D200 with the vertical grip fits more snug or give us an extra pick of cushioning material to place under the lens of camera's that sit so high. I had to place a rolled up sock under my lens since it doesn't sit right in the bag with the vertical grip attached.
