I'm a brand new DSLR (Pentax K10D) owner and did not know how much case I needed to haul around my camera plus "stuff". I like to have everything I need in organized places and I hate to pack and repack based on the occasion.The case is excellent in general. It's made of strong material with lots of padding and compartments inside that have flexible dimensions (left and right)based on movable dividers. You can divide the interior into 1 to 3 compartments but if you put in your DSLR with lens attached, plus one spare lens, the remaining room is very tight. You can squeeze some filters or cables in the remaining space (or a flash attachment but not both) but it didn't make me comfortable. I want padding and protection, but didn't want to fill the bag so full that it was stretching the fabric.There is one zipper pocket inside that would accommodate thin items like notes and flash memory spares, but probably nothing with much thickness including filters or batteries.There are three pockets on the outside of the bag. One on the cover as it flips over to latch, and another on the back body, both about the same as the inside cover. A third pocket is attched to the outside front body of the case that is more robust and could accommodate some additional bulk.On both sides of the case some flexible net-like material is available for quick easy access.The closure clips and the strap connections are all plastic, but seem reasonably substantial to me if you don't put 50lbs of equipment in the bag.I really like this bag but felt it was somewhat too small for me. If you like to pack and repack for specific situations then it might be for you.I was impressed by the quality of the case so much that I bought a larger Nova 4AW and it meets all my needs, but it is a larger case. Both the 2AW and the 4AW will comfortably "carry-on" if you need to bring a camera with you on trips that include flying.
