Review: I bought this bag to use with the 7D. I haven't used it with any other camera although I suspect any camera would work. I only give this an a slightly above average rating because I don't like the way the top part where the camera goes. I don't like the camera compartment because you can't put a long lens in it. The compartment that hold the camera will only allow the camera with a telescoping lens and it won't hold the camera at all if you use the vertical grip. The elastic on the mesh pocket under the front flap does not retain it's firmness so if you open it too wide the contents will fall out. The part that holds the lenses is pretty good and of course customizabe but if you keep the lens hoods (inverted of course) on the lens I found it impossible to get 6 lenses in the compartment. I do like the side flaps. The side flaps are roomier than they look and I have even put my f2 100-300 IF lens inside even with the tripod collar. There is also a computer compartment on the back which is pretty roomy but not big enough to hold the computer power adapter and the computer too. I do love that that the backpack sets upright and that it doesn't exaclty look like a camera bag. I tried to use the front elastic straps to hold my Manfrotto tripod but they are not sturdy enough. There should have been a detachable pouch at the bottom to put the tripod feet into to help hold the weight like Tamrac and the other bag manufacturers use. All in all its not a bad product but I don't think it's worthy of more than just a slightly above average rating.
