I want to buy a camera backpack for hiking and traveling overseas. My original backpack is too small. Some backpacks hold equipment in the whole interior compartment (like Lowepro Trekker series), while some store equipment in the lower compartment only (eg Lowepro Rover series). I don't carry too much equipment, but the bag needs to carry a camera body (preferrably deep enough for a handgrip), 3 lenses, a flash (the big 550ex), and some room for personal belongings such as jacket, water, and food. The Trekker design can apparently hold more equipment. If I use the vacant compartment to store my water, jacket, etc, is it big enough? Or should I find a bag with the Rover design to store equipment and other things separately? I don't need to take a bazooka like 400mm, but it should be large enough to hold a 70-200mm tele.
