Tamrac 5782 Evolution Messenger 2 Photo/Laptop Bag (Black) Tamrac's Evolution 2 is a versatile, slim-profile messenger bag that converts from a camera bag to a briefcase. To convert it to a briefcase, simply remove the shuttle from the bag using the handles. A DSLR with a lens attached, a flash, and 1 to 2 additional lenses (including some 70-200mm f/2.8) are protected inside a foam-padded compartment called the "shuttle", which features adjustable, foam-padded dividers. A foam-padded compartment holds the iPad, most 10" screen Netbooks, and up to 11.6" screen laptops. The front zippered pocket has paraphernalia pockets to organize discs, business cards, a phone or iPod, pens, pencils and other items. A zippered pocket on the front flap is perfect for keeping keys and tickets readily accessible. Soft, foam-padding in the back provides cushioning while the shoulder strap allows the bag to be easily swung from back to front.
