The small black Airport Essentials Backpack from Think Tank makes a photographer's life easy since on the outside, it resembles an ordinary piece of luggage while the inside speaks differently. The pack is rated to hold your standard DSLR, 4-6 basic zooms plus your iPad and 13" laptop. It's sized to handle your 300mm f/2.8 so if you're a nature or sports shooter, you're covered.
