The black Airport Security V 2.0 Rolling Camera Bag from Think Tank can carry a ton of gear and then some. With a capacity of three DSLRs, seven lenses and two flashes, there's enough space for even the most demanding photographer to bring along everything he needs. The bag is large enough to store your 70-200mm f/2.8 lens upright as well as being able to house a 400mm f/2.8, 500mm f/4 or a Canon 600mm f/4 (not Nikon). If you use the optional Think Tank Artificial Intelligence 13 V3.0 or 15 V3.0 laptop cases, they will work with the optional Think Tank Airport Security Low Dividers that is a set of dividers about 2.0" (5.1 cm) shorter than the padded, movable dividers that come with bag. This allows you to place the computer safely on top of your gear. If you use the Artificial Intelligence 17 V3.0 laptop case, use of the Low Divider Set is not recommended.
The rear security cable and supplied padlock are valuable since they permit you to tether the bag to any immovable object. So if you're shooting in a reception hall, you can lock the bag to a table or column while you shoot. The front security cable and supplied combination lock permit you to secure the optional computer case to the stretchable front pocket of the bag. However, for maximum security, lock the zippers of the entire bag with that included combination lock.
Dual user-replaceable wheels are supported by a retractable handle and top and side grab handles. Think Tank will send you a free replacement set of wheels should you need them. The wheels are specially located on the outside edges of the bag to provide maximum stability. The wheel housings themselves are high to protect the wheels from the potential damage of stairs and city streets and curbs. For emergencies, the bag comes with shoulder straps that hide within a zippered rear pocket. If the terrain you're crossing doesn't suit itself to wheels, the straps give you the option to carry the bag instead. The bag is not a full-fledged backpack but the straps offer an alternative for situations that arise unexpectedly.
Your tripod or monopod can be held in one of two ways. The stretchable front pocket or tripod cup will secure the pod. Speaking of outdoor shooting on a tripod, the bag comes with a rain cover that can be rapidly deployed when the weather turns against you. It will also cover the tripod. A front zippered organizer pocket will hold small stuff like pens, pads and wallet. It has pull-out pockets that are subdivided for separating accessories.
The really neat feature of this bag is the security plate that has a unique number on it. If you register that number with Think Tank and your bag gets lost, there's a chance you might recover it when someone finds it. Other convenient features include a business card holder located under the retractable handle as well as another zippered pocket in the same place for your passport. This incredibly spacious, flexible and functional bag is backed by Think Tank's lifetime warranty against manufacturer's defects.
