I am looking for a nice camera backpack to store my D90 along with a lens or 2. Looking for it to be able to hold a laptop and a small storage compartment as well. I bought a Tamrec Adveture 9 but it just doesnt work. The compartment is WAY too deep. Accourding to the spec its supposed to be 6" but it actually measures out to a good 6.5". When I sit the camera in the center area there is just way too much room for the body to move around. The D90 is only about 4.5" high. I have been looking around online and most of the packs are around 6" deep. I can only see that working for big camera bodies like the D3 or something with a grip on it. Am I missing something? Why are all these packs so deep?
