A larger ThinkTank long lens backpack which takes a 600mm f/4 lens on its own or a 400mm f/2.8 with pro-sized DSLR body attached. The bag can be re-configured with the supplied divider set - this will then carry a pro body plus 5-8 lenses. It has a high quality harness, and extra support can be obtained by attaching a Pro Speed Belt. There are attachment points for a monopod or tripod, and additional Modular Think Tank pouches on the front of the pack and a water bottle holder. Inside is space for smaller accessories under the lid. This slimline, lightly padded and discreet bag is ideal for transporting your prized big lens on to a plane.
