I bought the cannon photo backpack and used it for a couple of weeks. It is okay, works as advertised. What I don't like about the bag is that I have to take it completely off and lay it down on a flat surface in order to be able to safe extract my camera. I recently purchased the Lowepro Slingshot 200 and found their design completely addressed this issue. I think the LowePro quality is considerably better too. Look at the Slingshot before you make up your mind to buy the Cannon photo backpack.
