Tamrac Adventure 9 camera backpack
All too often, camera bags, especially backpacks, end up being geared toward professionals, with enough room for a battalion of lenses and every accessory you could ever imagine. That's great if you are a pro, but most of us need to bring along some noncamera items on our outings, and don't want to have to haul more than one bag to do so. That's why Tamrac created the Adventure series of backpacks, which do double duty as camera bags and small daypacks, thanks to separate compartments on bottom and top, respectively.
Largest among the series is the Adventure 9, which can accommodate professional SLR bodies with vertical grips and large pro lenses, such as Canon's nice, big EF 70-200mm f/2.8L IS USM. The daypack portion isn't huge--measuring 11x8.75x6.5 inches--but you'd be surprised at what you can fit into it. Plus, a padded sleeve built into the back of the bag holds laptops with screens as large as 17 inches, though the somewhat thick Dell we tried was a tight fit. A removable pouch, large enough for a laptop power supply or similar-size items, also comes with the bag.
As you can usually expect from Tamrac, there is a great attention to detail in this seemingly simple backpack. For example, the bottom portion has three clips on the outside that can keep the compartment from flopping open if the zippers somehow come undone. But, they also come in handy if you only want to open the compartment half way. Since the company's patented Memory and Battery Management System finds its home inside the bottom compartment cover, Tamrac included the two small side clips for the compartment so you can easily access your batteries and memory cards without having to completely open the bottom hatch. Depending on how you choose to configure the padded dividers inside that compartment, this can also make quick lens changes a lot smoother, especially if you wear the backpack on your front as many pro photographers do: to rest your arms on the pack to help steady your shots.
